Abstract
Emphysematous cholecystitis is a potentially life-threatening variant of acute cholecystitis, characterized by the presence of gas in the gallbladder wall/lumen due to the proliferation of gas-producing bacteria. Symptoms include upper right quadrant pain, fever, nausea, and vomiting. Laboratory tests may show nonspecific indications of systemic infection, and radiological assessment, especially CT scanning, is crucial for diagnosis. This case underscores the significance of early diagnosis and intervention in managing emphysematous cholecystitis to prevent serious complications and reduce the higher mortality rate compared to acute cholecystitis.

Abstract
Eosinophilic gastroenteritis (EoGE) is a group of infrequent conditions that arise from the accumulation of eosinophils in the gastrointestinal (GI) tract without any secondary causes of eosinophilia. Most cases of EoGE cases show involvement of different parts of the GI tract. Herein, we report a case of EoGE with the sole involvement of Jejunum. A 57-year-old male patient presented to our center with a chief complaint of acute abdominal pain. The patient had experienced chronic abdominal pain and intermittent diarrhea for several years, but he presented to the emergency department with severe acute flank pain. The patient was first diagnosed with renal stone and treated accordingly. However, the computed tomography (CT) scan also showed other incidental findings related to his chronic abdominal pain from several years ago, including mesenteric infiltration which shows fluid appearance in some areas, mild wall thickening, and mucosal edema of the duodenum and jejunal loops with normal appearance of the ileum. Complete blood count (CBC) showed increased eosinophil (15.5%) and decreased lymphocytes (13.1%) percent. Pathological examination of enteroscopy samples of jejunum showed a mild increase in the number of eosinophils in lamina propria. Neither parasites nor granuloma was detected. However, no such changes were found in other parts of the GI tracts. Based on pathological examination, the patient was diagnosed with eosinophilic enteritis of the jejunum. EoGE does not typically involve a specific part of the GI and generally affects both the stomach and intestine. This study reported the first case of EoGE where only the jejunal part of the intestine was involved and other parts of the GI tract were spared.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is characterized by accumulation of fat in the liver cells caused by means other than alcohol consumption. It is one of the most common chronic liver diseases worldwide and can lead to severe conditions, such as cirrhosis and liver cancer. NAFLD is often associated with other metabolic disorders, such as obesity and diabetes, and is closely related to lifestyle factors, such as diet and physical activity [1]. The diagnosis as well as management of NAFLD are complex and involve a multidisciplinary approach. The available treatment options include lifestyle modifications, pharmacological interventions, and in severe cases, liver transplantation. The increasing prevalence of NAFLD highlights the urgent requirement of effective prevention and management strategies. This disease is a growing health concern in India, given the rise in the incidence of obesity and diabetes. According to a study published in the Journal of Clinical and Experimental Hepatology in 2020, the prevalence of NAFLD in India is estimated to be between 9% and 32%. In accordance with the research population and diagnostic criteria employed, a study published in the Indian Journal of Gastroenterology in 2019 found that the prevalence of NAFLD in India ranged from 9.6% to 32.3% [2]. The same study also revealed that the prevalence of non-alcoholic steatohepatitis (NASH), a highly severe form of NAFLD, ranged from 1.5% to 8.4%. These statistics highlight the need for increased awareness and preventive measures to manage the growing burden of NAFLD in India.

Abstract
OBJECTIVES It is unclear which selection strategy, plain CT vs. CT perfusion (CTP), is more powerful in predicting outcome after mechanical thrombectomy (MT). We aimed to compare the effect of plain CT and CTP in predicting outcome after MT within 6 h. METHODS We conducted a prospective analysis of a retrospective cohort from our single-center study, which had occlusion of the internal carotid artery and middle cerebral artery up to the proximal M2 segment and received MT within 6 h. According to the Alberta Stroke Program Early CT Score (ASPECTS), patients were divided into a high-ASPECTS group (≥ 6) and a low ASPECTS group (< 6). Similarly, patients were divided into mismatch and no-mismatch groups according to the DEFUSE3 criteria for CTP. A good outcome was defined as a 90-day modified Rankin Scale (mRS) score of ≤ 3. Univariate and binary logistic regression analyses were used to investigate the association between different imaging modality and 90-day mRS score, and mortalities, respectively. RESULTS The high ASPECTS group included 307 patients (89.2%). The mismatch group included 189 (54.9%) patients meeting the DEFUSE3 criterion. Compared to the low ASPECTS group, the high ASPECTS group had a good outcome (odds ratio (OR), 2.285; [95% confidence interval (CI) (1.106, 4.723)], p = 0.026) and lower mortality (OR, 0.350; [95% CI (0.163, 0.752)], p = 0.007). However, there were no significant differences in good outcomes and mortality between the mismatch and no-mismatch groups. CONCLUSIONS Compared with plain CT, CTP does not provide additional benefits in the selection of patients suitable for MT within 6 h. CLINICAL RELEVANCE STATEMENT CT perfusion is not superior to plain CT for the prediction of clinical outcomes when selecting patients for mechanical thrombectomy in the first 6 h. In that clinical setting, plain CT may be safe in the absence of perfusion data. KEY POINTS • The advantage of CT perfusion (CTP) over CT in pre-mechanical thrombectomy (MT) screening has not been proven for patients with a large infarct core. • CTP is not better than plain CT in predicting good outcome following MT within 6 h. • Plain CT is sufficient for selecting patients suitable for MT within 6 h of large artery occlusion.

Abstract
Objectives To analyze the gender, age and side association of cochlear duct length in Pakistani-Asian cochlear implant recipient population based on computed tomography imaging study. Methods Current study retrospectively studied charts of cases who underwent cochlear implantation at the Department of Otolaryngology & Auditory Implant Centre, Capital Hospital Islamabad, over a period of two years from 1st May 2017 to 30th April 2019. These included 200 cases of both genders and of any age. In addition to basic demographic data, computed tomography findings of the temporal bone were utilized to measure the cochlear duct length. Data was analyzed using SPSS Version 23. Results Study revealed a mean Cochlear duct length of 29.935±2.173mm (range: 25.12 to 37.60) with significant (p<0.001) association with gender with longer cochlear duct in males compared to females on right (30.50±2.384 vs. 29.36±1.887) and on left side (30.50±2.236 vs.29.32±1.935). However, no significant difference was noted for side with slightly longer cochlear duct on the right side compared to left (29.95±2.224 vs.29.92±2.171). Also, no significant association with age was noted with p=0.578 & p=0.824 for right and left side respectively. Conclusion Pakistani population is characterized by a short mean CDL of 29.935±2.173 mm with significant association (p<0.001) with gender with longer cochlear duct length in males; and side with larger CDL on right side. However, no significant association with age was noted.

Abstract
Lymphangiomas are benign lesions of vascular origin with lymphatic differentiation, most commonly found in the head and neck. Generalized lymphangiomatosis is a very rare condition in adults, which is characterized by a diffuse proliferation of lymphatic vessels. The lymphangioma is composed of lymphatic endothelium-lined cystic spaces. This condition can be histologically differentiated from other vascular disorders such as cavernous or capillary hemangioma. However, many cases of lymphangioma can be confused with other vascular disorders, because of overlapping histologic findings. radiologic examinations, such as CT scan and MR imaging, are useful for assessing the morphologic feature and also the extent of disease, it is important to know the radiologic findings of generalized lymphangiomatosis. In this paper, we report a case of generalized lymphangiomatosis in a 42-year-old male who presented with left flank pain and hematuria. The first differential diagnosis was renal colic; hence he underwent an abdominopelvic computed tomography scan (CT scan). In the performed CT scan multiple cystic lesions were seen in the liver and spleen. Also, lytic lesions were seen in bones. CT-guided biopsy was performed and the result was compatible with generalized lymphangiomatosis, confirmed by cytology. Generalized lymphangiomatosis is a rarely reported disease in children and young adults. Delayed diagnosis in older patients or misdiagnosis is common due to its rarity and nonspecific clinical presentation. Different imaging modalities can incidentally diagnose the disease in asymptomatic patients. So radiologists should be aware of the disease manifestations in imaging modalities to diagnose the disease sooner and help the clinician start the therapy if needed.

Abstract
INTRODUCTION The management of thoracoabdominal (TA) gunshot wounds (GSW) remains challenging. This study reviewed our experience with treating such injuries over a decade. MATERIALS AND METHODS A retrospective study was conducted at a major trauma centre in South Africa over a ten-year period from December 2012 to January 2022. RESULTS Two hundred sixteen cases were included (male: 85 %, mean age: 33 years). Median RTS: 8 and median ISS: 17 (IQR: 10-19). The mean value of physiological parameters: Heart Rate (HR): 98/min, Systolic Blood Pressure (SBP): 119 mmHg, Temperature (T): 36.2 °C, pH: 7.35, Lactate 3.7 mmol/l. Ninety-nine (46 %) underwent a CT scan of the torso. One hundred fifty-four cases (69 %) were managed operatively: thoracotomy only [5/154 (3 %)], laparotomy only [143/154 (93 %)], and combined thoracotomy and laparotomy [6/154 (4 %)]. Those who had surgery following preoperative CT had a lower rate of dual cavity exploration (2 % vs 4 %, p = 0.51), although it did not reach statistical significance. The overall morbidity was 30 % (69). 82 % required intensive care (ICU) admission. The mean length of hospital stay was 14 days. The overall mortality was 13 % (28). Over the 10-year study period, there was a steady increase in the number of cases of TA GSWs managed at our institution. Over the study period, an increasing use of CT was noted, along with a steady reduction in the proportion of operations performed. CONCLUSIONS Thoraco-abdominal GSWs remain challenging to manage and continue to be associated with significant morbidity and mortality. The increased use of CT scans has reduced the degree of clinical confusion around which body cavity to prioritize, leading to an apparent decrease in dual cavity exploration, and has allowed for the increased use of minimalistic and non-operative approaches.

Abstract
PURPOSE The prospective study aimed to examine the central retinal artery (CRA) using computed tomography (CT). MATERIALS AND METHODS Seventy adult outpatients comprising 32 men and 38 women, at a mean age of 60.6 ± 13.3 years, were enrolled in the study. The patients underwent contrast-enhanced CT. The scan timing was set to start 5.0 s after the circle of Willis began to be delineated. RESULTS The ophthalmic arteries (OphAs) were comfortably delineated in all. In 97% of the patients, the CRA was delineated from the original site on the OphA to a more distal segment coursing on the optic sheath. Unilateral and bilateral CRA delineations were observed in 44% and 53% of cases, respectively. The delineated CRAs demonstrated highly variable morphologies in terms of the course and length on the optic sheath. In addition, the distance between the original site of the CRA and the posterior limit of the bulb was measured. The mean distance was 18.6 ± 5.0 mm on the right and 17.8 ± 4.3 mm on the left, respectively. No significant right-to-left differences in the measurements (p > 0.05) were observed. CONCLUSIONS If optimal scan timing is adopted, the CRA segments coursing on the optic sheath can be delineated using contrast-enhanced CT. CT may be a useful diagnostic modality for the CRAs and associated pathological conditions.

Abstract
Background Extraosseous Ewing sarcoma (EES) is a rare case that accounts for 20% of Ewing sarcoma cases. EES is the second most prevalent pediatric malignancy after peripheral primitive neuroectodermal tumors. EES mostly arise from soft tissue and extra-skeletal. Computed tomography (CT) and magnetic resonance imaging (MRI) are primary modalities for determining tumor location, characteristics, type, and extent of tumors. In addition, for presurgical management, radio intervention with arterial embolization is needed as a preoperative. Case Description We present a case of a 15-year-old boy diagnosed with EES. He had a "horn-like" tumor that grew progressively on his right ear over 5 months. Head CT scan and MRI were conducted to assess the extent. Embolization was performed before surgery. The surgery was conducted to excise the tumor radically. The histology pathology examination showed EES. Conclusion EES rarely occurs in the head and neck. This may manifest as a solid mass with bleeding components that destroy the nearby bones, with exophytic mass. Imaging is important for early finding and detecting complications of EES.

Abstract
Objectives Mild head injury is defined as a pediatric Glasgow Coma Scale (GCS) score of 13-15 at admission following head trauma. There are no clear indications for neuroimaging in such children. The aim of our study was to analyze the correlation of symptoms commonly encountered following mild head injury with any abnormality on the computed tomography (CT) scan. Materials and Methods This is a retrospective and observational study done in a tertiary care hospital. Records of all the children fulfilling the inclusion criteria were retrieved. Demographic details such as age, gender, and type of injury (hit by a blunt object, fall from height, and road traffic accident), symptoms such as presence and number of episodes of vomiting, presence and duration of loss of consciousness (LOC), presence of drowsiness, headache, giddiness, seizures, focal deficits and the GCS score, and CT scan findings were noted in a predesigned proforma. A CT scan with any of the following abnormalities such as skull fracture, cerebral edema, intracranial bleed (epidural hematoma, subdural hematoma, intracerebral hematoma, and subarachnoid hemorrhage), and cerebral contusion was considered as abnormal. Any neurosurgical intervention done was also noted. Results A total of 134 children in the age group of 1 month to 18 years with mild head injury were included in this study. The median (interquartile range) age of the children was 5 (2, 8) years, with majority being males. Road traffic accidents (34.3%) were the most common cause of injury, followed by fall from lesser than 3 feet height (31.3%). The most common symptoms were vomiting (43.6%), scalp/facial abrasions (37.2%), and LOC (31.9%). CT scan was abnormal in 53.7% of the cases, with skull fracture (35.1%) being the most common finding, followed by cerebral edema (13.4%). Among all the symptoms, ear/nosebleed or cerebrospinal fluid (CSF) otorrhea/rhinorrhea had a statistically significant association with a positive CT scan with P = 0.05 and an odds ratio of 1.4 (95% confidence interval, 1-1.9). Conclusion Children with mild head injury presenting with clinical features such as bleeding from the ear or nose and CSF otorrhea/rhinorrhea are more likely to have an abnormal CT scan. Hence, such children require close neurological observation and prompt intervention if necessary. However, abnormality on CT scan cannot be reliably ruled out based on the symptoms alone.

Abstract
Objectives Anticoagulants and antiplatelet (ACAP) agents are increasingly and frequently used, especially in the elderly. The present study was carried out to assess the prevalence of delayed traumatic intracranial hemorrhage (dtICH) after a normal result on an initial head computed tomography (CT) in adults who were taking ACAP medication. Materials and Methods The present retrospective included all adult patients who arrived in the emergency department between January 2017 and January 2021 with a history of fall from the patient's own height, while being on ACAP medication with an isolated head injury. The Institutional Review Board approved the study with a waiver of consent. The primary outcome measures were prevalence of dtICH in patients who had initial normal CT scan brain and were on ACAP medication. Results There were 2137 patients on ACAP medication, of which 1062 were male, and 1075 were of the female gender. The mean age of the patients was 82.1 years. About 8.2% had positive first CT scans (176/2137), while 0.023 (27/1149) had dtICH. The most common positive finding on the CT scan was subarachnoid hemorrhage followed by subdural hemorrhage. Male gender positively correlated with increased risk for first CT being positive (P = 0.033). Patient's with comorbidity of cirrhosis and chemotherapy had higher risk of dtICH (P = 0.47, 0.011). Conclusion There was a very low (0.023%) prevalence of dtICH. Dual therapy or Coumadin therapy made up the majority of tICH. Cirrhosis and chemotherapy were associated with the risk of a repeat CT scan being positive with an initial CT scan negative.

Abstract
PURPOSE Use of computed tomography (CT) scans raises safety concern as lifetime cumulative ionising radiation exposure is associated with risk of developing malignancies. This study aimed to investigate use of abdominal CT scans in the Danish health care sector. METHODS Data on abdominal CT scans performed annually in the North Denmark Region between 2005 and 2018 were extracted from the regional registry with emphasis on patients with a medical history of a repeated abdominal CT scan within 28 days. An audit of the medical files was subsequently conducted in 100 randomly selected patient cases to evaluate clinical information being provided, in addition to justification for a repeated abdominal CT scan, and finally if other radiology modalities could have been applied. RESULTS Number of annually performed abdominal CT scans in this demographically stable regional population increased by a factor 4.3 from 15 in 2005 to 65 in 2018 per 1,000 inhabitants. The audit revealed that 31% of the secondabdominal CT scans within a 28 days period were categorized as either doubtful whether justified or not justified. Moreover, 20% of theCT scans were considered replaceable by ultrasonography. CONCLUSIONS Annual performance of abdominal CT scans increased fourfold during the 14 years period. This tendency is probably attributable to changes in the Danish health care sector by which CT scan examination are used more frequently aiming at more accelerated patient investigation flow in conjunction with shorter length of hospitalization stay. Alertness is strongly warranted towards the associated risk of cancer due to life-time cumulative ionising radiation exposure by this strategy.

Abstract
RATIONALE AND OBJECTIVES Rhino‑Orbital‑Cerebral Mucormycosis (ROCM) is a life-threatening opportunistic fungal infection, which mostly affects immunocompromised patients. There has been a notable rise in the incidence of ROCM during the COVID-19 outbreak. In this study we described imaging characteristics of ROCM in detail, from early sinonasal inflammation to late intracranial involvement. MATERIALS AND METHODS In this retrospective study, Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) of 48 patients with proven ROCM in biopsy or culture were evaluated. All the patients had a history of COVID-19 infection within the previous three months. The imaging findings were described and the frequency of different parameters was reported. RESULTS Paranasal inflammation was detected in all the patients on imaging. The most common involved paranasal sinuses were ethmoid sinuses (97.9%). On diffusionweighted images, restricted diffusion was seen in the paranasal sinuses of 81.1% of the patients. In addition, sinus wall bone involvement was observed in 87.5% of the cases. The most common anatomical sites for extrasinus involvement were the retroantral soft tissue (89.6%) and orbital cavity (87.5%). Dacryocystitis in 50%, optic nerve inflammation in 43.2%, globe involvement in 18.9%, and trigeminal nerve involvement in 16% of the patients were detected. There was extension of inflammation through the cavernous sinuses and alongside the internal carotid arteries in 24% of the patients. CONCLUSION Characteristic imaging findings of ROCM not only play a vital role in the early diagnosis of this infection, but they also contribute to the assessment of the extension of inflammation, which is vitally important in surgical planning.

Abstract
BACKGROUND Hearing success in bimodally hearing patients with a cochlear implant (CI) and a hearing aid (HA) exhibits different results: while some benefit from bimodal CI and HA, others do not. OBJECTIVE The aim of this study was to investigate hearing success in terms of speech perception in bimodally fitted patients in relation to the cochlear coverage (CC) of the CI electrodes. MATERIALS AND METHODS Using the OTOPLAN software (CAScination AG, Bern, Switzerland), CC was retrospectively measured from CT scans of the temporal bone of 39 patients, who were then categorized into two groups: CC ≤ 65% (CC500) and CC > 65% (CC600). Monaural speech intelligibility for monosyllables at a sound pressure level (SPL) of 65 dB in open field was assessed at various timepoints, preoperatively with HA and postoperatively with CI, and compared between the groups. In addition, speech intelligibility was correlated with CC in the entire cohort before surgery and during follow-up (FU). RESULTS Overall, no significant differences in speech intelligibility were found between CC500 and CC600 patients at any of the FU timepoints. However, both CC500 and CC600 patients showed a steady improvement in speech intelligibility after implantation. While CC600 patients tended to show an earlier improvement in speech intelligibility, CC500 patients tended to show a slower improvement during the first 3 months and a steeper learning curve thereafter. The two patient groups converged during FU, with no significant differences in speech intelligibility. There was no significant relationship between unimodal/unilateral free-field speech intelligibility and CC. However, patients with a CC of 70-75% achieved maximum speech intelligibility. CONCLUSION Despite a nonsignificant correlation between CC and speech discrimination, patients seem to reach their maximum in unimodal/unilateral speech understanding mainly at 70-75% coverage. However, there is room for further investigation, as CC500 was associated with a shorter cochlear duct length (CDL), and long and very long electrodes were used in both groups.

Abstract
Correct tumour restaging is pivotal for identifying the most personalised surgical treatment for patients with locally advanced rectal cancer undergoing neoadjuvant therapy, and works to avoid both poor oncological outcome and overtreatment. Digital rectal examination, endoscopy, and pelvic magnetic resonance imaging are the recommended modalities for local tumour restaging, while chest and abdominal computed tomography are utilised for the assessment of distant disease. The optimal length of time between neoadjuvant treatment and restaging, in terms of both oncological safety and clinical effectiveness of treatment, remains unclear, especially for patients receiving prolonged total neoadjuvant therapy. The timely identification of patients who are radioresistant and at risk of disease progression remains challenging.

Abstract
PURPOSE To investigate the radiologic prevalence of otic capsule dehiscence in temporal bone computed tomography (CT) scan. METHODS This was a cross-sectional study. The temporal bone CT scans of the patients presenting to a tertiary center were evaluated for possible dehiscence in any part of the otic capsule; then, all of the dehiscence were confirmed by a trained academic radiologist. For each type of otic capsule dehiscence, at least three planes were used with a specific type of reconstruction. When a dehiscence was present in at least two consecutive images in all planes, it was considered as a true dehiscence. RESULTS Six hundred patients (mean age: 40 ± 18.1 years) were enrolled. The prevalence of superior and posterior semicircular canal dehiscence was 6.0% and 2.7%, respectively. The prevalence of cochlear-facial dehiscence, cochlear-internal auditory canal dehiscence, and cochlear-carotid dehiscence was 6.3%, 0.7%, and 0.7%, respectively. The prevalence of vestibular aqueduct-jugular bulb dehiscence was 6.3% and the prevalence of posterior semicircular canal-jugular bulb dehiscence was 0.2%. CONCLUSIONS Considering different types of otic capsule dehiscence described, care should be taken in patients with vestibular and auditory signs and symptoms to diagnose these dehiscences.

Abstract
BACKGROUND/OBJECTIVES Radiological evidence of focal pancreatic parenchymal atrophy (FPPA) may presage early pancreatic ductal adenocarcinoma (PDAC) development. We aimed to clarify the incidence of FPPA and the clinicopathological features of PDAC with FPPA before diagnosis. METHODS Data on endoscopic ultrasound-guided fine-needle biopsies and surgical samples from 170 patients with pancreatic cancer histologically diagnosed between 2014 and 2019 were extracted from the pathology database of Komagome Hospital and Juntendo University hospital and retrospectively evaluated together with 51 patients without PDAC. RESULTS FPPA was identified in 47/170 (28%) patients before PDAC diagnosis and in 2/51 (4%) patients in the control group (P < 0.01). The median duration from FPPA detection to diagnosis was 35 (interquartile range [IQR]:16-63) months. In 24/47 (51%) patients with FPPA, the atrophic area resolved. The lesion was in the head and body/tail in 7/40 and 67/56 of the patients with (n = 47) and without FPPA (n = 123), respectively (P < 0.001). Histopathologically confirmed non-invasive lesions in the main pancreatic duct and a positive surgical margin in the resected specimens occurred in 53% vs. 21% (P = 0.078) and 29% vs. 3% (P = 0.001) of the groups, respectively. The PDAC patients with FPPA accompanied by a malignant pancreatic resection margin had high-grade pancreatic intraepithelial neoplasia. CONCLUSIONS FPPA occurred in 28% of the PDAC group at 35 months prediagnosis. The FPPA area resolved before PDAC onset. Benchmarking previous images of the pancreas with the focus on FPPA may enable prediction of PDAC. PDAC with FPPA involves widespread high-grade pancreatic intraepithelial neoplasia requiring a wide surgical margin for surgical excision.

Abstract
In order to diagnose chronic rhinosinusitis (CRS), diagnostic nasal endoscopy (DNE) and computed tomography (CT) scan both are important investigations. But both have their pros and cons, some findings are seen better in DNE and others in CT. Our study aims to correlate DNE and CT findings. 50 patients with CRS were included in this observational prospective study done at tertiary care hospital. Preoperative each patient underwent DNE and got CT scan followed by scoring using Lund Kennedy and Lund Mackay grading respectively. Functional Endoscopic Sinus Surgery (FESS) was performed and intraoperative findings were correlated with CT scan for each of them. The sensitivity of endoscopy was 93.18% and the specificity was 83.33%. Positive predictive value of DNE was 97.62% and negative predictive value was 62.50%. Most of the endoscopy positive patients of CRS were CT positive. Also, the sensitivity of CT PNS was highest for all groups of sinus disease while specificity was high for posterior group of sinuses (81.82%) and frontal sinus (89.19%). Both DNE and CT scan should be used for planning the management of CRS. DNE tells better about middle meatal secretions, condition of mucosa, polyps. But in situations where due to anatomical variation DNE is difficult, CT scan helps us. CT identifies the extent of disease, the anatomical variants and vital relations of PNS. Overdiagnosis through CT is checked by DNE.

Abstract
Pancreatic adenocarcinoma is often discovered at an advanced stage due to a lack of early symptomology, resulting in this being the fourth leading cause of cancer-related death in the USA. The relationship between diabetes mellitus and pancreatic cancer has been known for many years; however, it is not well understood. Studies have suggested that long-standing type 2 diabetes mellitus can increase the risk of pancreatic cancer by 1.5-2.0-fold. However, patients with new-onset diabetes over 50 years of age have an 8-fold higher risk of pancreatic cancer. Evidence has shown that pancreatic cancer causes diabetes, with the majority being new onset. Diabetic ketoacidosis, which occurs in long-term hyperglycemia, as an initial presentation of pancreatic adenocarcinoma is rare, and only a few cases have been reported. It is postulated that pancreatic cancer prevents insulin-producing cells of the pancreas from responding to insulin resistance. The enriching new-onset diabetes for pancreatic cancer (ENDPAC) score may be utilized as a screening tool for pancreatic carcinomas as an early diagnosis may lead to cure by surgery instead of the grave prognosis associated with it. In this case report, we discuss a 52-year-old female presenting with symptoms of diabetic ketoacidosis who was then subsequently found to have stage-4 pancreatic adenocarcinoma. We concluded that if a patient presents with new-onset diabetes, abdominal imaging with CT scans and endoscopic ultrasound may be warranted to rule out pancreatic carcinoma.

Abstract
Objectives Intracranial pressure (ICP) monitoring in patients with intracranial tumors undergoing craniotomy is usually done in perioperative period in intensive care unit. Invasive measurement of ICP, though considered as the gold standard, has its own limitations such as availability of expertise, equipment, and associated complications. Period of raised ICP in post-operative period may impact patient outcomes. Post-craniotomy computed tomography (CT) assessment is done routinely and may need to be repeated if indicated during post-operative stay. Utility of sonographic serial optic nerve sheath diameter (ONSD) assessment in post-operative monitoring of patients who have undergone elective craniotomy was explored in this study. The primary objective of the study was to measure the dynamic change in ONSD as compared to baseline pre-operative measurement in the first 3 postoperative days after elective craniotomy. The secondary objective of the study was to evaluate correlation between ONSD value with Glasgow Coma Scale (GCS) and post-operative CT findings. Materials and Methods In this prospective, observational, and cohort study, we studied adult patients undergoing craniotomy for intracranial tumors. GCS assessment and sonographic measurement of ONSD were done preoperatively, immediate post-operative period, and 12, 24, and 48 h after surgery. CT scan to detect raised ICP was done at 24 h post-operative. Correlation of ONSD with GCS at respective period and correlation of CT scan finding with respective ONSD assessment were evaluated. Results A total of 57 patients underwent elective craniotomy for intracranial tumors. Significant difference was observed in ONSD value depending on time of measurement perioperatively (χ2 = 78.9, P = 0.00). There was initial increase in the first 12 h followed by decrease in ONSD in the next 48 h. Negative correlation was observed between baseline ONSD and 12 h GCS (ρ = -0.345, P = 0.013). There was significant change in GCS scores based on the status of ONSD (raised or normal) at 12 h after surgery (P = 0.014). Significant correlation between USG ONSD and CT ONSD was observed (ρ = 0.928, P = 0.000). Optimal cutoff value of ONSD to detect raised ICP with reference to CT signs was 4.8 mm with 80% sensitivity and 95% specificity. Conclusion ONSD undergoes dynamic changes, correlates with CT scan, and has good diagnostic accuracy to detect raised ICP post-craniotomy for intracranial tumors. It may serve as a useful tool in monitoring in resource-limited setup.

Abstract
BACKGROUND The establishment of a risk-appropriate care approach for pregnant women and newborn infants under the COVID-19 pneumonia is vital to prevent the main pregnancy complications. OBJECTIVES AND DESIGN This study reviewed the vertical transmission (VT) potential of COVID-19 pneumonia in pregnant women. Key-related symptoms and adverse clinical outcomes for mothers and infants before and after childbirth were summarized. Some practical therapies and preventive health solutions were also proposed. RESULTS There was a high susceptibility in pregnant women to COVID-19 infection, especially in the third trimester of pregnancy. The most common symptoms in 22-40-year-old patients infected with COVID-19 were fever (87.6%), cough (52.3%), dyspnea (27.6%), fatigue (22.4%), sore throat (13.5%), malaise (9.4%), and diarrhea (3.4%), respectively. The viral infection led to an increase in preterm labor and cesarean delivery without any intrauterine infection and severe neonatal asphyxia. No infection in the newborn infants was reported despite a high risk of the VT phenomenon. The most important therapies were the reception of antiviral and antibiotic drugs, oxygenation therapy, psychological interventions, and food supplements with health-promoting effects. The best proposed medical strategies to control the COVID-19 infection were bi-monthly screening and following-up the mothers' and fetuses' health, not using the potent broad-spectrum antibiotics and corticosteroids, providing the delivery room with negative pressure for emergency cesarean section, and the immediate isolation of newborns after childbirth without direct breastfeeding. CONCLUSION Babies with respiratory problems may be born to some mothers with COVID-19, who have weak immune systems. Thus, the virus transmission cycle should be disrupted to prevent adverse maternal and fetal outcomes by integrating individual health guidelines, efficient medical care therapies, and hospital preventive practices.

Abstract
Introduction Tracheocele or tracheal diverticulum is an uncommon benign entity that can be congenital or acquired. It is usually diagnosed incidentally on cervicothoracic imaging. Our aim is to describe the etiopathogenic, clinical and paraclinical features of the tracheocele as well as its therapeutic modalities. Case Report We report 2 cases of asymptomatic congenital tracheocele occurred in a boy and a woman, incidentally found on cervical CT scan done for accidental ingestion of chicken bone and infected thyroid hematocele respectively. The tracheocele, in our 2 cases, was probably congenital: no risk factors were noted and the opening of the tracheocele was narrow. The tracheocele was located in the right posterolateral tracheal wall in the 2 cases. It communicated with the tracheal lumen in one case. The female patient underwent a right lobectomy and resection of the tracheocele. For the boy, our attitude was conservative. The evolution was uneventful in the 2 cases. Conclusions The presence or absence of risk factors, CT scan, bronchoscopy and histologic exam may distinguish between congenital and acquired forms. Asymptomatic patients are managed conservatively. Surgical resection is the treatment of choice for symptomatic patients.

Abstract
BACKGROUND Ordering of computed tomography (CT) scans needs to consideration of diagnostic utility as well as resource utilisation and radiation exposure. Several factors influence ordering decisions, including evidence-based clinical decision support tools to rule out serious disease. The aim of this qualitative study was to explore factors influencing Emergency Department (ED) doctors' decisions to order CT of the head or cervical spine. METHODS In-depth semi-structured interviews were conducted with purposively selected ED doctors from two affiliated public hospitals. An interview tool with 10 questions, including three hypothetical scenarios, was developed and validated to guide discussions. Interviews were audio recorded, transcribed verbatim, and compared with field notes. Transcribed data were imported into NVivo Release 1.3 to facilitate coding and thematic analysis. RESULTS In total 21 doctors participated in semi-structured interviews between February and December 2020; mean interview duration was 35 min. Data saturation was reached. Participants ranged from first-year interns to experienced consultants. Five overarching emerging themes were: 1) health system and local context, 2) work structure and support, 3) professional practices and responsibility, 4) reliable patient information, and 5) holistic patient-centred care. Mapping of themes and sub-themes against a behaviour change model provided a basis for future interventions. CONCLUSIONS CT ordering is complex and multifaceted. Multiple factors are considered by ED doctors during decisions to order CT scans for head or c-spine injuries. Increased education on the use of clinical decision support tools and an overall strategy to improve awareness of low-value care is needed. Strategies to reduce low-yield CT ordering will need to be sustainable, sophisticated and supportive to achieve lasting change.

Abstract
Background and Objectives Bacterial involvement in chronic rhinosinusitis (CRS) condition made it difficult to treat using available antibiotic therapy. Therapeutic ultrasound was investigated here to evaluate bacterial diversity and quantity before and after continuous/pulsed ultrasound strategy compared to control patients. Materials and Methods Totally, 34 CRS patients were studied in three groups, including continuous ultrasound, pulsed ultrasound and control. Bacterial culture and identification were done before and after treatment. Computed tomography scan (CT scan) and questionnaire scores were recorded two times before and after intervention. Results The most prevalent bacterial isolates were non-hemolytic Streptococci (34 patients), coagulase-negative Staphylococcus (33 patients), Gram-negative cocci (26 patients), Staphylococcus aureus (19 patients), Streptococcus pneumoniae (five patients) and Streptococcus pyogenes (five patients). Both continuous and pulsed ultrasound could significantly reduce the quantity of bacterial isolates after treatment. CT scan and questionnaire results support the effectiveness of therapeutic ultrasound. Conclusion The quantity of clinically important bacteria was significantly reduced using ultrasound treatment and recovery of patients was supported by CT scan and questionnaire scores. Alternative therapeutic ultrasound could be an effective procedure in CRS patients.

Abstract
BACKGROUND COVID 19 may affect organs other than lungs, including liver, leading to parenchymal changes. These changes are best assessed by unenhanced computed tomography (CT). We aim to investigate the effect of COVID 19 on liver parenchyma by measuring the attenuation in CT scan Hounsfield unit (HU). MATERIALS AND METHODS A cohort of patients, who tested COVID 19 polymerase chain reaction positive, were enrolled and divided into two groups: fatty liver (FL) group (HU ≤ 40) and nonfatty liver (NFL) group (HU > 40) according to liver parenchyma attenuation measurements by high resolution noncontrast CT scan. The CT scan was performed on admission and on follow up (10-14 days later). Liver enzyme tests were submitted on admission and follow up. RESULTS Three hundred and two patients were enrolled. Liver HU increased significantly from 48.9 on admission to 53.4 on follow up CT scan (P<0.001) in all patients. This increase was more significant in the FL group (increased from 31.9 to 42.9 [P =0.018]) Liver enzymes were abnormal in 22.6% of the full cohort. However, there was no significant change in liver enzymes between the admission and follow up in both groups. CONCLUSION The use of unenhanced CT scan for assessment of liver parenchymal represents an objective and noninvasive method. The significant changes in parenchymal HU are not always accompanied by significant changes in liver enzymes. Increased HU values caused by COVID 19 may be due to either a decrease in the fat or an increase in the fibrosis in the liver.

Abstract
INTRODUCTION Sarcopenia is defined as both low muscle function (performance or strength) and low muscle mass. Although aging is the main cause of sarcopenia, it can also occur due to poor nutrition and chronic diseases like liver cirrhosis, chronic kidney disease, and diabetes. OBJECTIVE To do the quantitative analysis of various normative skeletal muscle indices (to define sarcopenia) in the Indian population. METHODS Sex-specific means, standard deviations (SD), and sarcopenia cutoffs (mean-2SD) of psoas muscle thickness (PMTH), psoas muscle area (PMA), psoas muscle index (PMI), erector spinae muscle area (ESMA), skeletal muscle radiation attenuation (SMRA), total skeletal muscle area (SMA), and total skeletal muscle index (SMI) were computed. RESULTS A total of 2002 individuals (1308 males and 694 females) underwent CT evaluation. PMTH (mm/m) was observed to be 15.87±2.67 in males vs. 12.61±2.46 in females (p=0.0001); PMA (cm2) was 18.55±3.45 in males vs.13.52±2.80 in females (p=0.0001); PMI (cm2/m2) was 6.69±1.40 in males vs. 5.57±1.18 in females (p=0.0001); ESMA (cm2) was 45.74±6.01 in males vs. 35.37±5.63 in females (p=0.0001); ESMI (cm2/m2) was 16.5±2.55 in males vs. 14.62±2.6 in females (p=0.0001); SMRA was 55.80±3.91 Hounsfield unit (HU) in males vs. 52.36±3.67 HU in females (p=0.0001); SMA (cm2) was 147.73±11.77 in males vs. 106.33±12.00 in females (p=0.0001); and SMI (cm2/m2) was estimated to be 51.00±5.70 in males vs. 43.93±6.05 in females (p=0.0001). PMTH, PMI, ESMI, SMI, and SMRA cutoffs for sarcopenia at L3 were observed to be 10.53 mm/m, 3.89 cm2/m2, 11.40 cm2/m2, 39.59 cm2/m2, and 47.98 HU among males and 7.69, 3.20, 9.42, 31.83, and 45.01 among females, respectively; these values were consistent with previously reported cutoffs in Indian studies but not consistent with the cutoffs reported in other countries. CONCLUSION Normative values of skeletal muscle indices for either sex among the Indian adult population would enable future studies on sarcopenia in various medical conditions.

Abstract
UNLABELLED Currently, in young children with minor traumatic head injuries (MTHI) classified as intermediate risk (IR), PECARN recommends clinical observation over computer tomography (CT) scan depending on provider comfort, although both options being possible. In this study, we describe clinicians' choice and which factors were associated with this decision. This was a planned sub-study of a prospective multicenter observational study that enrolled 1006 children younger than 18 years with MTHI who presented to six emergency departments in The Netherlands. Of those, 280 children classified as IR group fulfilling one or more minor criteria, leaving the clinician with the choice between clinical observation and a CT scan. In our cohort, 228/280 (81%) children were admitted for clinical observation, 15/280 (5.4%) received a CT scan, 6/280 (2.1%) received a CT scan and were admitted for observation, and 31/280 (11%) children were discharged from the emergency department without any intervention. Three objective factors were associated with a CT scan, namely age above 2 years, the presence of any loss of consciousness (LOC), and presentation on weekend days. CONCLUSION In children with MTHI in an IR group, clinicians prefer clinical observation above performing a CT scan. Older age, day of presentation, and any loss of consciousness are factors associated with a CT scan. WHAT IS KNOWN • Clinical decision rules have been developed in the management of children of different risk groups with minor traumatic head injury (MTHI). • According to the Dutch national, clinical decision rules in children under 6 years of age up to 50% of children classify as intermediate risk (IR) and clinicians may choose between clinical observation and computed tomography (CT). WHAT IS NEW • In this IR group, clinical observation is chosen in 81% children with MTHI. • In the subgroup where clinicians performed a CT scan, children were older and presented more frequently on a weekend day, and more frequently consciousness was lost.

Abstract
BACKGROUND Abdominal lymphangiomatosis is a rare benign condition accounting for less than 1% of all the cases of lymphangiomatosis. Management usually involves radical surgical excision; however, depending upon the extent of involvement, patient condition, and absence of complications, conservative management can be also considered.
CASE SUMMARY We present the case of a 32-year-old male who presented with short onset abdominal pain and melena. Physical examination findings were within normal limits, except for left lower abdominal tenderness. Upper gastrointestinal endoscopy was within normal limits. Abdominal and pelvic ultrasound and computed tomography (CT) scan revealed numerous, variably-sized cystic lesions within the abdominal cavity, exclusively and extensively affecting the small bowel mesentery with sparing of the retroperitoneum. The diagnosis was confirmed by CT and cytological examination. Radical surgical excision was technically impossible in this patient because of the extensive involvement of the mesentery; therefore, the patient was managed conservatively.
CONCLUSION Extensive and exclusive small bowel mesentery involvement in abdominal lymphangiomatosis is rare. Imaging modalities play an important role in establishing the diagnosis and conservative management can be considered when surgery is technically impossible.

Abstract
Ganglioneuroma is a rare, differentiated, and benign neurogenic tumor that could grow into a huge size with minimal or no symptoms at all. Ganglioneuroma is typically found in older children or adults and is commonly detected within the posterior mediastinum (other than retroperitoneal). Here, we present a case of a 3-year-old patient with shortness of breath, and radiological examination showed a giant mediastinal tumor which proved to be a ganglioneuroma after histopathological examination. This study highlights the possibility of ganglioneuroma occurring in younger children and the role of imaging in assessing ganglioneuroma as a posterior mediastinal tumor.

Abstract
INTRODUCTION Expediting notification of lesions in acute ischemic stroke (AIS) is critical. Limited availability of experts to assess such lesions and delays in large vessel occlusion (LVO) recognition can negatively affect outcomes. Artificial intelligence (AI) may aid LVO recognition and treatment. This study aims to evaluate the performance of an AI-based algorithm for LVO detection in AIS. METHODS Retrospective analysis of a database of AIS patients admitted in a single center between 2014 and 2019. Vascular neurologists graded computed tomography angiographies (CTAs) for presence and site of LVO. Studies were analyzed by the Viz-LVO Algorithm® version 1.4 - neural network programmed to detect occlusions from the internal carotid artery terminus (ICA-T) to the Sylvian fissure. Comparisons between human versus AI-based readings were done by test characteristic analysis and Cohen's kappa. Primary analysis included ICA-T and/or middle cerebral artery (MCA)-M1 LVOs versus non-LVOs/more distal occlusions. Secondary analysis included MCA-M2 occlusions. RESULTS 610 CTAs were analyzed. The AI algorithm rejected 2.5% of the CTAs due to poor quality, which were excluded from the analysis. Viz-LVO identified ICA-T and MCA-M1 LVOs with a sensitivity of 87.6%, specificity of 88.5%, and accuracy of 87.9% (AUC 0.88, 95% CI: 0.85-0.92, p < 0.001). Cohen's kappa was 0.74. In the secondary analysis, the algorithm yielded a sensitivity of 80.3%, specificity of 88.5%, and accuracy of 82.7%. The mean run time of the algorithm was 2.78 ± 0.5 min. CONCLUSION Automated AI reading allows for fast and accurate identification of LVO strokes with timely notification to emergency teams, enabling quick decision-making for reperfusion therapies or transfer to specialized centers if needed.

Abstract
Purpose We investigated if the stress applied to the lung during non-invasive respiratory support may contribute to the coronavirus disease 2019 (COVID-19) progression. Methods Single-center, prospective, cohort study of 140 consecutive COVID-19 pneumonia patients treated in high-dependency unit with continuous positive airway pressure (n = 131) or non-invasive ventilation (n = 9). We measured quantitative lung computed tomography, esophageal pressure swings and total lung stress. Results Patients were divided in five subgroups based on their baseline PaO2/FiO2 (day 1): non-CARDS (median PaO2/FiO2 361 mmHg, IQR [323–379]), mild (224 mmHg [211–249]), mild-moderate (173 mmHg [164–185]), moderate-severe (126 mmHg [114–138]) and severe (88 mmHg [86–99], p < 0.001). Each subgroup had similar median lung weight: 1215 g [1083–1294], 1153 [888–1321], 968 [858–1253], 1060 [869–1269], and 1127 [937–1193] (p = 0.37). They also had similar non-aerated tissue fraction: 10.4% [5.9–13.7], 9.6 [7.1–15.8], 9.4 [5.8–16.7], 8.4 [6.7–12.3] and 9.4 [5.9–13.8], respectively (p = 0.85). Treatment failure of CPAP/NIV occurred in 34 patients (24.3%). Only three variables, at day one, distinguished patients with negative outcome: PaO2/FiO2 ratio (OR 0.99 [0.98–0.99], p = 0.02), esophageal pressure swing (OR 1.13 [1.01–1.27], p = 0.032) and total stress (OR 1.17 [1.06–1.31], p = 0.004). When these three variables were evaluated together in a multivariate logistic regression analysis, only the total stress was independently associated with negative outcome (OR 1.16 [1.01–1.33], p = 0.032). Conclusions In early COVID-19 pneumonia, hypoxemia is not linked to computed tomography (CT) pathoanatomy, differently from typical ARDS. High lung stress was independently associated with the failure of non-invasive respiratory support.

Abstract
Obturator hernia is a rare type of pelvic hernia and considers more common in female patients. The obturator canal is a narrow space, leading to high chances of bowel strangulation. It is rarely diagnoses, especially on the left side. The mortality rate of obturator hernia is high due to delayed diagnosis. We are presenting a case of a 70-year-old woman, admitted with the clinical features of acute intestinal obstruction. On clinical examination, she had a nontender, distended abdomen, and all hernial orifices were normal. Per rectal and vaginal examination was also normal. She diagnosed a left-sided obturator hernia with the help of a computed tomography scan abdomen. We should consider a differential diagnosis of obturator hernia, especially in old, thin-built female patients with recurrent episodes of obstructive features. Early diagnosis and timely operative intervention may reduce the chances of complications and mortality.

Abstract
PURPOSE Most mild traumatic brain injuries (TBIs) can be treated conservatively. However, some patients deteriorate during observation. Therefore, we tried to evaluate the characteristics of deterioration and requirement for further management in mild TBI patients. METHODS From 1/1/2017 to 12/31/2017, patients with mild TBI and positive results on CT scans of the brain were retrospectively studied. Patients with and without neurological deteriorations were compared. The characteristics of mild TBI patients with further neurological deterioration or the requirement for interventions were delineated. RESULTS One hundred ninety-two patients were enrolled. Twenty-three (12.0%) had neurological deteriorations. The proportions of deterioration occurring within 24 h, 48 h and 72 h were 23.5, 41.2 and 58%, respectively. Deteriorated patients were significantly older than those without neurological deteriorations (69.7 vs. 60.2; p = 0.020). More associated extracranial injuries were observed in deteriorated patients [injury severity score (ISS): 20.2 vs. 15.9; p = 0.005). Significantly higher proportions of intraventricular hemorrhage (8.7 vs. 1.2%; p = 0.018) and multiple lesions (78.3 vs. 53.8%; p = 0.027) were observed on the CT scans of patients with neurological deteriorations. Subset analysis showed that deteriorated patients who required neurosurgical interventions (N = 7) had significantly more initial GCS defects (13 or 14) (71.4 vs. 12.5%; p = 0.005) and more initial decreased muscle power of extremities (85.7 vs. 18.8%; p = 0.002). CONCLUSION More attention should be given to mild TBI patients with older age, GCS defects, decreased muscle power of the extremities, multiple lesions on CT scans and other systemic injuries (high ISS). Most deteriorations occur within 72 h after trauma.

Abstract
OBJECTIVE To map OTA/AO type 43C3 tibial pilon fractures by means of computed tomography and analyze the difference between varus and valgus fractures. We hypothesized that valgus fractures are less frequent than varus, and the affected zones of the tibial pilon are different among the patterns. MATERIAL AND METHODS Retrospective, cross-sectional, observational study, using images of 73 computed tomographies of patients who had presented OTA/AO type 43C3 tibial pilon fractures. The radiographs and computed tomography were subdivided into two groups: varus and valgus fractures. Also, the presence or absence of fibula fractures. Both groups were subdivided into eight zones: four lateral to the pilon and four medial. RESULTS The distribution of total affected zones is significantly different in the male and female subgroups (p = 0.027). The incidence of cases in zone 1 is significantly different in varus and valgus displacement subgroups (p = 0.002). In the patients with valgus displacements, 61.9% of the fractures affect zone 1; in the patients with varus displacements, only 25.8% of the fractures affect zone 1. In the patients without fibula fracture, 58.3% of the fractures affect zone 2; in the patients with fibula fracture, 24.6% of the fractures affect zone 2. CONCLUSION The typical profile of the patient with a pilon fracture is age ranging from 27 to 57 years, male, with fibular fracture, and the injury affecting two or three pilon zones, with zones 6, 1, and 3 being the most affected ones. There is no typicality regarding the valgus or varus fracture displacement, although a difference was found in zone 1.

Abstract
As we continue to fight against the current coronavirus disease-2019 (COVID-19) pandemic, healthcare professionals across the globe are trying to answer questions surrounding how to best help patients with the up-to-date available science while awaiting the development of new therapies and mass vaccination. Since early in the pandemic, studies indicated a heightened risk of venous thromboembolism (VTE) in COVID-19 infected patients. There have been differing expert opinions about how to assess pretest probability of VTE in this patient population. This has been partly due to the high prevalence of respiratory failure in this patient population and the use of D-dimer as a prognostic test which is also frequently elevated in patients with COVID-19 in absence of VTE. Some experts have argued for an approach similar to usual care with testing if clinical suspicion is high enough. Some have argued for more routine screening at different points of care. Others have even suggested empiric therapeutic anti-coagulation in moderate to severely ill COVID-19 patients. In the following article, we review and summarize the most current literature in hopes of assisting clinicians in decision making and guidance for when to be concerned for VTE in COVID-19 patients. We also discuss research gaps and share pathways currently being used within our institution.

Abstract
Malleolar ankle fractures have been classified using plain radiographs, and there is no consensus regarding the role of computed tomography (CT) scans in preoperative planning. We analyzed critical aspects, such as limits of standard radiographs, types of injury, classification methods and cost/benefit evaluations. CT scans allow a 3D analysis of the fracture to be obtained and consequently assess the indication for surgical procedure, surgical access and the type of fixation devices required. This exam is useful for detecting lesions that may go unnoticed on radiographs and will help surgeons to clarify the pathoanatomy of ankle fractures. According to Arbeitsgemeinschaft fur Osteosynthesefragen/ Orthopaedic Trauma Association (AO/OTA) classification, CT scan is recommended in medial malleolar fractures with vertical rim, type 44B fractures with posterior malleolar involvement and all type 44C fractures (according to AO/OTA). Also Tillaux-Chaput fractures (43-B1 according to AO/OTA), malleolar fractures in the presence of distal tibial fractures (43 according to AO/OTA) and distal tibia fractures in adolescents should be studied with CT scans.

Abstract
Introduction The trends in the incidence and age of onset of first stroke is lacking in Ghana and with an increasing elderly population, such trends are projected to increase in developing countries. Through the review of Computed Tomography (CT) scan examinations and patients’ records; we assessed the incidence rate and age of onset of first stroke in Cape Coast Metropolis. Methods This study retrospectively reviewed all imaging records and clinical data of all stroke patients referred for CT scans in the radiology department of the Cape Coast Teaching Hospital (CCTH) between January 2017 and December 2019. All CT confirmed cases of stroke were classified as either hemorrhagic stroke or ischemic stroke. Age adjusted annual incidence rate with 95% Confidence Intervals (CIs) were calculated assuming a Poisson distribution. Mean difference were tested using one way Analysis of Variance (ANOVA). Results 840 patients with first onset of stroke were identified, comprising 417 (49.6%) males and 423 (50.4%) females. There was a statistically significant difference in the mean age of onset of first stroke in males (61.47 ± 13.36 years) and in females (63.41 ± 15.41 years), p = 0.049. The incidence of first stroke for the entire age categories were higher in males compared to the same age categories in females, except for patients aged 35–44 years in 2017, 25–34 years in 2018, 15–24 years and 75 years or older age groups in 2019. Males had hemorrhagic stroke at an older age (64.41 ± 15.31 years) compared to ischemic stroke (60.40 ± 12.42 years) in this study. This difference was statistically significant (p = 0.014). There was no significant difference in the mean age of onset of first stroke for the respective years under study: F (3, 836) = 0.693, P = 0.500. Conclusion The findings of this study imply that the incidence rate of stroke is higher in males than in females and increases with age. The majority of the strokes were ischemic.

Abstract
Arachnoiditis ossificans of the spine is a rare entity defined as an ossification of the leptomeninges resulting in neurologic decline. We describe the case of a 42-year-old woman, without any obvious predisposing factor, who presented with a progressive cauda equina syndrome. The imaging findings on magnetic resonance imaging were confusing by showing an atypical intraspinal lesion extending from L1 to S1. The computed tomography scan was more specific by showing suggestive images of a huge arachnoiditis ossificans of the lumbar spine. The patient underwent a large lumbar laminectomy with an incomplete resection of the ossified arachnoid. The histologic study confirmed the bony nature of the lesion. This illustrative case highlights the importance of helical computed tomography scan with multiplanar reconstruction for the diagnosis of arachnoiditis ossificans.

Abstract
A male patient with severe pneumonia due to coronavirus disease 2019 (COVID-19) had acute respiratory distress syndrome (ARDS) which developed in the second week since the first symptoms and improved without mechanical ventilation. The patient had epilepsy as a comorbid disease and his routinely consumed antiepileptic drugs were likely to cause alterations of the immune system. Ground-glass opacity (GGO), consolidation, and reticular pattern are typical radiological features of COVID-19 pneumonia. Less common findings were septal thickening, bronchiectasis, pleural thickening, and subpleural involvement. These radiological abnormalities evolve throughout the course of the disease. In this case report, a GGO lesion was seen in thin-section CT scans on the 30th and 45th day since the onset of symptoms. The consolidation subsided with time and on the 65th day, minimal GGO was seen in CT scan without pulmonary fibrosis and bronchiectasis.

Abstract
BACKGROUND An anatomical double bundle ACL reconstruction replicates the anatomy of native ACL as the tunnels are made to simulate the anatomy of ACL with AM and PL bundle foot prints. The goal of anatomic ACL reconstruction is to tailor the procedure to each patient's anatomic, biomechanical and functional demands to provide the best possible outcome. The shift from single bundle to double bundle technique and also from transtibial to transportal method has been to provide near anatomic tunnel positions. PURPOSE To determine the position of femoral and tibial tunnels prepared by double bundle ACL reconstruction using three dimensional Computed tomography. STUDY DESIGN A prospective case series involving forty patients with ACL tear who underwent transportal double bundle ACL reconstruction. METHOD Computed tomography scans were performed on forty knees that had undergone double bundle anterior cruciate ligament reconstruction. Three-dimensional computed tomography reconstruction models of the knee joint were prepared and aligned into an anatomical coordinate axis system for femur and tibia respectively. Tibial tunnel centres were measured in the anterior-to-posterior and medial-to-lateral directions on the top view of tibial plateau and femoral tunnel centres were measured in posterior to anterior and proximal-to-distal directions with anatomic coordinate axis method. These measurements were compared with published reference data. RESULTS Analysing the Femoral tunnel, the mean posterior-to-anterior distances for anteromedial and posterolateral tunnel centre position were 46.8% ± 7.4% and 34.5% ± 5.0% of the posterior-to-anterior height of the medial wall and the mean proximal-to-distal distances for the anteromedial and posterolateral tunnel centre position were 24.1% ± 7.1% and 61.6% ± 4.8%. On the tibial side, the mean anterior-to-posterior distances for the anteromedial and posterolateral tunnel centre position were 28.8% ± 4.3% and 46.2% ± 3.6% of the anterior-to posterior depth of the tibia measured from the anterior border and the mean medial-to-lateral distances for the anteromedial and posterolateral tunnel centre position were 46.5% ± 2.9% and 50.6% ± 2.8% of the medial-to-lateral width of the tibia measured from the medial border. There is high Inter-observer and Intra-observer reliability (Intra-class correlation coefficient). DISCUSSION AND CONCLUSION Femoral AM tunnel was positioned significantly anterior and nearly proximal whereas the femoral PL tunnel was positioned significantly anterior and nearly distal with respect to the anatomic site. Location of tibial AM tunnel was nearly posterior and nearly medial whereas the location of tibial PL tunnel was very similar to the anatomic site Evaluation of location of tunnels through the anatomic co-ordinate axes method on 3D CT models is a reliable and reproducible method. This method would help the surgeons to aim for anatomic placement of the tunnels. It also shows that there is scope for improvement of femoral tunnel in double bundle ACL reconstruction through transportal technique.

Abstract
OBJECTIVE To determine the prevalence and features of inner ear anomalies in children with congenital profound hearing loss who presented at our cochlear implant center based on imaging studies. METHODS This retrospective study reviewed charts of children with congenital SNHL, who presented to Department of Otolaryngology & Auditory Implant Centre, Capital Hospital Islamabad over a period of 2 years from 1st May 2017 to 30th April 2019. These included 481 cases of both genders aged between 1 to 12 years. After gathering demographic data, audiological data, computed tomography findings of the temporal bone were analyzed. Data was analyzed using SPSS 22. RESULTS The Inner Ear Malformations were identified in 48(10%) children including 28 (58.33%) males and 20 (41.67%) female. Most 20(41.67%) presented at >3-5 years of age followed by 19(39.58%) at 2-3 years. However, no significant association of gender (p=0.57, p=0.076) and age of presentation (p=0.344, p=0.697) for right and left ears was noted with inner ear malformations. The most common anomaly noted were CLA, CH-III and CH-II in decreasing order of frequency in both ears. CONCLUSION The prevalence of IEM's was found to be 48(10%). Commonest anomalies noted were CLA, CH-III and CH-II. No significant association of gender and age of presentation was noted with type of anomaly in both ears.

Abstract
BACKGROUND The conventional approach for external ventricular drainage (EVD) application is the freehand method. Technical devices can improve the accuracy of placement, but they have not yet replaced anatomical landmarks owing to the cost and effort that they entail. There is disagreement as to whether freehand EVD application is safe enough to be accepted as a standard technique. Many authors have investigated the final catheter position in retrospect. They describe variable rates of malpositioning. However, few studies have assessed in how far cranial surface anatomy has really been respected during burr-hole drilling and catheter insertion. The aim of this study was to investigate parameters that might play a part in determining the final intracranial catheter position. METHODS In all, 100 pre- and postprocedural thin-layer computed-tomography (CT) scans of EVD patients were analysed with the help of JiveX® and OsiriX Lite® software. A series of anatomical and catheter-related parameters, including inter alia intraventricular blood, midline shift, burr-hole location and catheter entrance angle, were correlated with the final catheter position. RESULTS A majority of EVDs show an optimal or nearly optimal position. Only the deviation of catheter entrance angle has a significant influence on catheter malpositioning. The burr-hole location can vary within an area of several centimetres around the coronary suture. CONCLUSIONS The freehand application of EVD is safe as long as the intracranial anatomy is not disfigured to a large extent, the surface measurements are carried out precisely and the puncturing is done perpendicularly to the skull.

Abstract
Background and aim To investigate sex differences with respect to presence and location of atherosclerosis in acute ischemic stroke patients. Methods Participants with acute ischemic stroke were included from the Dutch acute stroke trial, a large prospective multicenter cohort study performed between May 2009 and August 2013. All patients received computed tomography/computed tomography-angiography within 9 h of stroke onset. We assessed presence of atherosclerosis in the intra- and extracranial internal carotid and vertebrobasilar arteries. In addition, we determined the burden of intracranial atherosclerosis by quantifying internal carotid and vertebrobasilar artery calcifications, resulting in calcium volumes. Prevalence ratios between women and men were calculated with Poisson regression analysis and adjusted prevalence ratio for potential confounders (age, hypertension, hyperlipidemia, diabetes, smoking, and alcohol use). Results We included 1397 patients with a mean age of 67 years, of whom 600 (43%) were women. Presence of atherosclerosis in intracranial vessel segments was found as frequently in women as in men (71% versus 72%, adjusted prevalence ratio 0.95; 95% CI 0.89–1.01). In addition, intracranial calcification volume did not differ between women and men in both intracranial internal carotid (large burden 35% versus 33%, adjusted prevalence ratio 0.93; 95% CI 0.73–1.19) and vertebrobasilar arteries (large burden 26% versus 40%, adjusted prevalence ratio 0.69; 95% CI 0.41–1.12). Extracranial atherosclerosis was less common in women than in men (74% versus 81%, adjusted prevalence ratio 0.86; 95% CI 0.81–0.92). Conclusions In patients with acute ischemic stroke the prevalence of intracranial atherosclerosis does not differ between women and men, while extracranial atherosclerosis is less often present in women compared with men.

Abstract
The purpose of this study is to review the published literature for the range of radiographic findings present in patients suffering from coronavirus disease 2019 infection. This novel corona virus is currently the cause of a worldwide pandemic. Pulmonary symptoms and signs dominate the clinical picture and radiologists are called upon to evaluate chest radiographs (CXR) and computed tomography (CT) images to assess for infiltrates and to define their extent, distribution and progression. Multiple studies attempt to characterize the disease course by looking at the timing of imaging relative to the onset of symptoms. In general, plain CXR show bilateral disease with a tendency toward the lung periphery and have an appearance most consistent with viral pneumonia. Chest CT images are most notable for showing bilateral and peripheral ground glass and consolidated opacities and are marked by an absence of concomitant pulmonary nodules, cavitation, adenopathy and pleural effusions. Published literature mentioning organ systems aside from pulmonary manifestations are relatively less common, yet present and are addressed in this review. Similarly, publications focusing on imaging modalities aside from CXR and chest CT are sparse in this evolving crisis and are likewise addressed in this review. The role of imaging is examined as it is currently being debated in the medical community, which is not at all surprising considering the highly infectious nature of Severe Acute Respiratory Syndrome coronavirus 2.

Abstract
Descending necrotizing mediastinitis (DNM) is a medical emergency with a high associated morbidity and mortality. DNM may arise secondary to primary odontogenic or neck infection in susceptible patients and it may spread contiguously via the “danger” space to the mediastinum. This case report is focused on complications following an odontogenic infection in a healthy 48-year-old male that led to a massive inflammation associated an extensive empyema. After chest and neck computed tomographic scan a diagnosis of cervical necrotizing fasciitis with DNM was made. A multidisciplinary approach with an urgent surgical intervention and the finding of the right antibiotic therapy resulted to be successful. After 2 weeks the patient was dismissed in better health condition.

Abstract
Computed tomography (CT) scanning is the gold standard when estimating pleural effusion volume; however, the procedure exposes patients to ionizing radiation. Our study was aimed at developing ultrasound-based calculation models that can quantify the volume of pleural effusion in seated patients and validating each model using volumetric chest CT analyses as reference. Our study enrolled 36 hospitalized patients who underwent a chest CT scan and ultrasound, in the seated position, with the aid of a convex probe. To estimate the volume of pleural effusions, we applied one linear and two multiplanar ultrasound-based equations using a CT reconstruction as reference. Testing these models in our validation set (n = 16), we determined that 0.42 was the R2 coefficient for the linear equation, and 0.97 and 0.98, respectively, were the R2 coefficients for the cylindrical-sector models, and observed that the latter had the lowest dispersion of data and an optimal intraclass correlation coefficient. We then concluded that multiplanar ultrasound-based equations are accurate and reliable in estimating pleural effusions and outperform previously developed equations.

Abstract
Background: Optic nerve sheath diameter (ONSD) measurement is emerging as a noninvasive method to estimate raised ICP. It is helpful in situations where imaging of brain or direct ICP monitoring is not available or feasible. Use of ONSD is still limited, so this study was planned to determine whether the bedside sonographic measurement of ONSD can reliably predict elevated ICP in neuro-trauma patients. Methodology: After approval from Hospital Ethics Committee, this cross-sectional study was conducted in hundred traumatic brain injury (TBI) patients with suspected elevated ICP, admitted to neurosurgical ICU. The severity of brain injury was assessed according to Glasgow coma scale (GCS), initial CT scan findings, and revised trauma score (RTS). All patients underwent ONSD sonography of the eye and CT scan subsequently. ONSD of ≥5.0 mm was considered as a benchmark of raised ICP. Results: Mean ONSD of the study group with ONSD ≥5.0 mm was 5.6 ± 0.3 mm. ONSD was raised in 46% of patients, more so in patients with low GCS (3-6). The relationship of ONSD with GCS, CT scan findings, and RTS was highly significant. The sensitivity of the bedside sonographic measurement ONSD to detect raised ICP was 93.2% and specificity was 91.1% when compared with CT scan. Positive Predictive Value of the ONSD measurement was 89.1% and the negative predictive value was 94.4%. Conclusion: Ultrasonographic assessment of ONSD is a reliable modality to detect raised ICP in neurotrauma patients. It can be helpful in the early initiation of treatment of elevated ICP, thus preventing secondary brain damage.
