Wandering Spleen Torsion: A Diagnostic Challenge

Wandering spleen, or hypermobile spleen, arises from the elongation or maldevelopment of the spleen's suspensory ligaments. This condition is a rare clinical entity, primarily affecting children, with a higher prevalence among adult females in the active reproductive age group. Manifestations may include an asymptomatic abdominal mass or intermittent abdominal discomfort due to the torsion and subsequent spontaneous detorsion of the spleen. This case report details the presentation of a 14-year-old female initially misdiagnosed as having gastroenteritis who later experienced acute abdomen. Subsequent ultrasonography and computed tomography scan revealed splenic torsion, confirmed during exploratory laparotomy, which demonstrated an infarcted spleen. The definitive therapeutic intervention was a total splenectomy. This clinical entity should be taken into account in the differential diagnosis of acute abdominal pain in order to aid in early diagnosis and management. This could allow us to avoid splenectomy whenever possible and instead do splenopexy, especially in pediatric cases, as the spleen plays a crucial role in the reticuloendothelial system.

An unusual case of Takayasu arteritis presenting with persistent cough in a young female patient: A case report

Takayasu arteritis (TA) is a chronic granulomatous inflammatory arteritis of large vessels. Females aged 20-40 are usually affected and the manifestations can range from asymptomatic disease to major cardiovascular and neurological abnormalities. Herein, we present a case of a 20-year-old female who had a persistent cough as the initial manifestation of an underlying TA. She had a free past medical history. The patient sought medical help multiple times and took many antibiotics with no improvement. Laboratory tests showed a marked elevation in inflammatory markers so the patient was admitted for further investigations. CT scan showed a circumferential mural thickening involving mainly the descending thoracic aorta which is highly suggestive of an underlying chronic granulomatous vasculitis behind this. Our patient was treated with a combination of corticosteroid and azathioprine and showed substantial improvement after 2 weeks. TA can present with various symptoms. Therefore, patients presenting with atypical symptoms and late-onset vascular symptoms need a high degree of suspicion with close follow-up to allow early detection of any complication.

Exploring Anatomical Variations of Abdominal Arteries Through Computed Tomography: Classification, Prevalence and Implications

BACKGROUND AND AIMS

Variations in the branches of the abdominal aorta are relatively prevalent and can impact certain surgeries. The accurate identification and differentiation of these variations pre- and intraoperatively are crucial to avoid negative clinical sequelae. This study aimed to investigate the prevalence of variations in some branches of the abdominal aorta and to identify the most frequent variants as well as any rare variants not previously classified in the existing classification systems. The study's findings may help improve the understanding and management of these variations.

MATERIALS AND METHODS

This retrospective study was conducted at the Department of Radiology at An-Najah National University Hospital (NNUH) and included 550 abdominal computed tomography (CT) angiographic scans for patients (51.5% males, 48.5% females) performed between January 2017 and January 2023.

RESULTS

Variations were most common in the hepatic arteries (34.7%), followed by the renal arteries (31.3%). Variations in the celiac trunk were the least frequent (9.8%). The gastro-splenic trunk (type V) was the most common celiac trunk variant. The most common hepatic artery variant was the replacement of the right hepatic artery (type III). Accessory renal arteries were more frequent on the left side and among males (P = 0.01). The celiac trunk variations had a significant association with the hepatic artery variations (P = 0.001) and the renal artery variations (P = 0.011), respectively.

CONCLUSION

There is a high prevalence of anatomical variations in the described vessels, and it matches the results in the reported literature. Our findings also suggest the possible coexistence of variants. We have also encountered rare variants, especially in the hepatic arterial system. Some of the hepatic arterial system variants are not included in the older classification systems, calling for an extension of the old systems (Michel's and Hiatt classification systems) or replacement with the newer (CRL or EX-CRL classification systems) to account for rare variants not previously classified. Radiologists and surgeons should be proficient in identifying and differentiating these variations to take precautions and actions for each variant individually.

Spontaneous ureteric perforation: A rare complication of tuberculosis

Genitourinary tuberculosis (GU TB) is a rare condition that has historically been described as a great imitator, owing to its variable and deceptive clinical presentation and course. GU TB may affect any part of the urological system and lead to serious complications such as kidney and ureteric damage. The diagnosis of GU TB requires high index of suspicion especially if complications occur. We describe the first case of spontaneous ureteric perforation secondary to GU TB as spontaneous bladder perforation was previously described.

Autoimmune pancreatitis with IgG-4 cholangiopathy in a pregnant woman: A case report

Diagnosis and management of autoimmune pancreatitis during pregnancy. Autoimmune pancreatitis is a rare and life-threatening condition with increased maternal and fetal morbidity and mortality. Autoimmune pancreatitis may result in a mass-forming lesion in the pancreas resembling pancreatic cancer; therefore, meticulous and careful investigations must be done to avoid misdiagnosing autoimmune pancreatitis as pancreatic cancer. Since autoimmune pancreatitis improves dramatically to steroid therapy, accurate diagnosis of autoimmune pancreatitis can avoid unnecessary procedures, surgeries, and pancreatic resection. A case of a pregnant lady in her third trimester was presented with abdominal pain, nausea, and vomiting. On examination, there was tenderness in both epigastric and right hypochondrium associated with elevated serum amylase, liver transaminases, alkaline phosphatase, gamma-glutamyl transpeptidase, and immunoglobulin G4. Both abdominal ultrasound and magnetic resonance cholangiopancreatography showed a pancreatic head lesion with dilation in both pancreatic duct and common bile duct. Steroid was initiated that resulted in rapid and dramatic responsiveness. Acute pancreatitis is uncommon during pregnancy, and autoimmune pancreatitis is a very rare form of acute pancreatitis; therefore, a clear and rapid assessment, diagnosis, and management plan are necessary to avoid maternal and fetal morbidity and mortality.

Clinical and Radiological Predictors of Early Intervention in Acute Ureteral Colic

PURPOSE

Acute ureteric colic (AUC) is generally one of the most common reasons for emergency department attendance. Expectant management is recommended in non-complicated ureteral calculi. However, data regarding the optimal duration of observation or indications of early intervention (EI) are not well understood. This article describes the clinical and radiological factors that promote EI in AUC.

PATIENTS AND METHODS

This was an observational and retrospective cohort study. Patients with AUC diagnosed based on non-contrast computerized tomography (NCCT) between 2019 and 2020 were enrolled in the study. These patients were classified into two main categories: spontaneous passage of stone (SSP) and EI. In addition, a comparative analysis was performed to identify clinical and radiological variables that promote EI.

RESULTS

One-hundred and sixty-one patients were included. High WBCs are associated with a significant increase in EI. Forty-three percent (n=37) of patients with serum WBCs higher than 10 had an EI, while 23% had SSP (n=17;p<0.001). High CRP level is also significantly associated with EI (n=36; 86%; p<0.001). Upper and middle ureteral calculi are statistically associated with EI (n=54; 62%) in comparison to the SSP cohort (n=22; 30%;p<0.001). EI is also linked to the maximal length of ureteric calculi (MCL) of 9 mm (6-13mm), and HU density of stone of 700 (430-990) H.U (p<0.001). Ureteric stone volume of 0.2 (0.06-0.3) cm³ is significantly associated with EI (p<0.001). Ureteral wall thickness of 3 (2-3 mm), the presence of extrarenal pelvis (n=20; 23%), and AP diameter of renal pelvis 18 (13-28 mm) are all significantly associated with a higher rate of EI (p<0.001). Multiple binary logistic regression analysis showed that MCL is the strongest predictor of EI.

CONCLUSION

MCL is an independent and robust predictor of EI in AUC. Biochemical variables and radiological characteristics can also act as an adjunct to promote EI.

An assessment of medical students' proficiency regarding the hazards of radiological examinations on the health of workers and patients: a cross-sectional study from Palestine

BACKGROUND

The use of radiological examination is increasing worldwide. Since radiation exposure can result in many health hazards, medical professionals, as well as medical students, should possess adequate knowledge regarding radiation and its related hazards to protect themselves and the patients. Many studies have assessed medical students' knowledge on this topic, but never in Palestine. In this study, we aimed to examine Palestinian medical students' awareness and knowledge regarding radiological examination modalities and their risks on themselves and their patients.

METHODS

This was an observational, cross-sectional, population-based study, conducted to assess the awareness of radiation exposure and its risks among Palestinian medical students. An online questionnaire was implemented on medical students at An-Najah National University. A total knowledge score that ranged from 0 to 22 was calculated for each participant, with higher scores indicating better knowledge regarding radiation doses and the related hazards.

RESULTS

Two hundred eighty and seven students participated in our study, with a response rate of 71%. The average knowledge score of the participants was 10.97 ± 4.31 out of a maximum of 22 points. Male participants and participants in advanced study years achieved better knowledge scores (p-values were 0.034 and < 0.001, respectively). Perceived radiology knowledge was significantly associated with the actual knowledge score among the participants (p-value< 0.001). Receiving radiology lectures in fourth and fifth years significantly affected the participants' knowledge score (p-values were < 0.001).

CONCLUSIONS

We found a severe lack of knowledge regarding radiation doses and related risks among medical students. Therefore, we recommend that medical schools update and supplement their curriculum regarding knowledge on radiation.
