Abstract
BACKGROUND Medulloblastomas are the most common malignant brain tumors in the pediatric population. Based on the idea that tumors with identical radio-genomic features should behave similarly, the four molecular subtypes are now widely accepted as a guide for the management and prognosis. The radiological features of medulloblastomas can predict the molecular subtype; thus, anticipating the subsequent disease progression. However, this has not been evaluated comprehensively. PURPOSE We aim to thoroughly study the association between the molecular subtypes and radiological features of medulloblastomas. Moreover, we aim to investigate the efficacy of this correlation with the use of progression-free survival (PFS) and five-year survival rates. METHODS A retrospective analysis was conducted for all histopathological confirmed medulloblastomas in pediatric patients (<16 years old) that were operated on in Kuwait over the past ten years (n=44). The radiological, histological, and molecular characteristics were justifiably evaluated and analyzed in our sample. RESULTS The overall progression-free survival after one year was noticed among 27 cases (≈44%) and the non-specific five-year survival was seen in 31 cases (≈70%) after a five-year follow-up. SHH and WNT had the best outcomes, while group 3 showed the worst outcomes. CONCLUSION Our findings did not support the association between most of the typical MRI characteristics and survival rate. We further established that SHH and WNT biological types have a better prognosis. There was no association observed between the radiographic features, specifically the location, and the molecular subtype.

Abstract
Splenic hamartomas (SHs) are uncommon, benign vascular lesions of unclear etiology and are mostly found incidentally on abdominal images, at surgery, or at autopsy. Since the first case description, in 1861, less than 50 pediatric SH cases have been reported in the literature. In this article, we have performed an analysis of all SH cases in children published in the literature to date and presented our case of an 8-year-old male with SH. These lesions in children were shown to cause symptoms more often than in the adult population. The observed SH sizes in children ranged from a few millimeters to 18 cm, and the symptomatic lesions were mostly larger or multiple. The most common clinical finding was splenomegaly. Signs of hypersplenism were present in children with a single SH larger than 4.5 cm (diameter range: 4.5-18.0 cm) and in those with multiple hamartomas, ranging from a few millimeters to 5 cm. Eighty percent of patients with available laboratory findings had hematological abnormalities such as anemia, thrombocytopenia, or pancytopenia. Other symptoms and signs included abdominal pain, recurrent infections, fever, night sweats, lethargy, growth retardation, and weight loss. The use of multiple imaging modalities may suggest the preoperative diagnosis of a splenic mass in children and determine the therapeutic approach. However, the final diagnosis of SH relies on histopathological evaluation. Surgery, including total or partial splenectomy (PS), is the mainstay of SH management. Although total splenectomy carries a greater risk of overwhelming post-splenectomy infection than PS it has remained the most performed surgical procedure in children with SH. In the majority of pediatric patients with symptomatic SH, resolution of symptoms and resolution or improvement of cytopenias occurred after surgical treatment.

Abstract
Primary dural lymphoma (PDL) constitutes a rare subgroup within central nervous system lymphomas, defined by its exclusive confinement to the dura mater, without a concurrent brain or systemic lymphatic involvement. This distinctive localization presents diagnostic challenges. In this report, we present a series of 3 cases where initial radiological presentations resembled meningiomas. We meticulously analyze key differentiating imaging characteristics, in CT, morphological MRI, and spectroscopy imaging. And show that recognizing and understanding these nuanced features are pivotal in enabling accurate differentiation of PDL and facilitating timely clinical intervention.

Abstract
Meningiomas are the most common extra-axial neoplasmof the central nervous system (CNS). There are a number of characteristic imaging features of meningiomas on magnetic resonance imaging (MRI) that allow an accurate diagnosis, however there are a number of atypical features that may be diagnostically challenging. Furthermore, a number of other neoplastic and non-neoplastic conditions may mimic meningiomas. This case highlights the importance of careful analysis of imaging findings and the need for consideration of all possible diagnoses, including rare or atypical presentations of common neoplasms such as meningiomas. Early detection and accurate diagnosis are crucial in determining the appropriate management and improving the outcomes for patients with intracranial tumors.

Abstract
Background Brain abscess (BA) is a rare but life-threatening infection. Early identification of the pathogen is helpful to improve the outcomes. This study aimed to describe the clinical and radiological features of patients with BA caused by different organisms. Methods A retrospective, observational study of patients with known etiologic diagnosis of BA in Huashan Hospital Affiliated to Fudan University in China between January 2015 and December 2020 was conducted. Data on patient demographics, clinical and radiological presenting features, microbiological results, surgical treatment, and outcomes were collected. Results Sixty-five patients (49 male, 16 female) with primary BAs were included. Frequent clinical presentations included headache (64.6%), fever (49.2%) and confusion (27.3%). Streptococcus viridans was associated with thicker wall of abscesses (6.94 ± 8.43 mm for S. viridans versus 3.66 ± 1.74 mm for other organisms, P = 0.031) and larger oedema (89.40 ± 15.70 mm for S. viridans versus 74.72 ± 19.70 mm for other organisms, P = 0.023). The independent factor associated with poor outcome identified by multivariate analysis was confusion (Odds ratio 6.215, 95% confidence interval 1.406-27.466; P = 0.016). Conclusions Patients with BAs caused by Streptococcus species had nonspecific clinical signs, but specific radiological features, which might be helpful for early diagnosis.

Abstract
Adult polyglucosan body disease (APBD) is caused by bi-allelic pathogenic variants in GBE1 and typically shows middle age onset urinary symptoms followed by progressive gait disturbances and possibly cognitive decline. Here we present a Belgian cohort of four patients from three families showing both classical and atypical signs of APBD. By clinical phenotyping, detailed neuroimaging of both central nervous system and skeletal muscle, genetic and biochemical testing, we confront our findings with the classical presentation of adult polyglucosan body disease and emphasize the importance of a multidisciplinary approach when diagnosing these patients.

Abstract
BACKGROUND Early singular nodular hepatocellular carcinoma (HCC) is an ideal surgical indication in clinical practice. However, almost half of the patients have tumor recurrence, and there is no reliable prognostic prediction tool. Besides, it is unclear whether preoperative neoadjuvant therapy is necessary for patients with early singular nodular HCC and which patient needs it. It is critical to identify the patients with high risk of recurrence and to treat these patients preoperatively with neoadjuvant therapy and thus, to improve the outcomes of these patients. The present study aimed to develop two prognostic models to preoperatively predict the recurrence-free survival (RFS) and overall survival (OS) in patients with singular nodular HCC by integrating the clinical data and radiological features. METHODS We retrospective recruited 211 patients with singular nodular HCC from December 2009 to January 2019 at Eastern Hepatobiliary Surgery Hospital (EHBH). They all met the surgical indications and underwent radical resection. We randomly divided the patients into the training cohort (n =132) and the validation cohort (n = 79). We established and validated multivariate Cox proportional hazard models by the preoperative clinicopathologic factors and radiological features for association with RFS and OS. By analyzing the receiver operating characteristic (ROC) curve, the discrimination accuracy of the models was compared with that of the traditional predictive models. RESULTS Our RFS model was based on HBV-DNA score, cirrhosis, tumor diameter and tumor capsule in imaging. RFS nomogram had fine calibration and discrimination capabilities, with a C-index of 0.74 (95% CI: 0.68-0.80). The OS nomogram, based on cirrhosis, tumor diameter and tumor capsule in imaging, had fine calibration and discrimination capabilities, with a C-index of 0.81 (95% CI: 0.74-0.87). The area under the receiver operating characteristic curve (AUC) of our model was larger than that of traditional liver cancer staging system, Korea model and Nomograms in Hepatectomy Patients with Hepatitis B Virus-Related Hepatocellular Carcinoma, indicating better discrimination capability. According to the models, we fitted the linear prediction equations. These results were validated in the validation cohort. CONCLUSIONS Compared with previous radiography model, the new-developed predictive model was concise and applicable to predict the postoperative survival of patients with singular nodular HCC. Our models may preoperatively identify patients with high risk of recurrence. These patients may benefit from neoadjuvant therapy which may improve the patients' outcomes.

Abstract
BACKGROUND Osteonecrosis of the femoral head (ONFH) is a multifactorial disease, and agnogenic ONFH, otherwise known as idiopathic ONFH, is rare in clinic. Idiopathic ONFH that exhibits severe necrosis and progresses extremely rapidly is called rapidly destructive hip disease (RDHD). RDHD greatly affects patients but is rarely reported in clinical practice and literature. CASE PRESENTATION In this study, a 64-year-old male patient with complete collapse and necrosis of the right femoral head complicated with severe bone destruction at 10 months after left total hip arthroplasty (THA) was reported. The period from the intact structure of the right femoral head to the first discovery of its complete collapse, according to imaging results, was 7 months. The duration from the occurrence of symptoms in the right hip joint to the first discovery of complete collapse and necrosis of the femoral head was only 5 months. At present, the cause has not been determined based on medical history, symptoms, signs, imaging evaluation results, laboratory examination results, and pathological examination results, though it has been identified as severe idiopathic aseptic necrosis of the femoral head with rapid progression, or RDHD. Finally, right THA was performed, and a good outcome was observed in the patient at present. CONCLUSIONS As a rare hip joint disease, RDHD greatly influences the normal life of patients. RDHD of the contralateral side after unilateral THA is even scarcer. Left THA may be one of the important factors accelerating the necrosis of the right femoral head. Hopefully, with this case report, more attention will be paid to the contralateral hip joint in patients undergoing unilateral THA by clinicians and rehabilitation physicians, and a clinical reference will be provided for the research on RDHD.

Abstract
BACKGROUND The spectrum of ground glass opacity (GGO) is a diagnostic and clinical management quandary. The role of computed tomographic scans in detecting malignant GGO has inter-observer variability. Pure GGO have been traditionally thought to be predominantly benign in nature and has long volume doubling times. This study was undertaken to correlate the findings of radiology and histology of ground glass opacities at our institute. METHODS This study is a retrospective observational study of patients who underwent lung resection surgery for radiology proven ground glass opacities between January 2010 and December 2018. A total of 115 patients were included in the study based on inclusion and exclusion criteria and were analysed. RESULTS The patients were divided into two groups; pure GGO (n = 50), mixed GGO (n = 65). The pathological tumour size was ≤ 2 cm in 51% of the patients and 27 patients had the size between 2.1 and 3.0 cm. The predominant histopathologic feature was lepidic predominance in 54 patients followed by 24 patients with acinar predominance. Among patients with radiological tumour size of ≤ 2 cm, pure GGO was present in 48% of the patients. Among patients with pure GGO, 96% of the patients had no solid component. 44 patients had only single CT scan before proceeding to surgery. All these patients had mixed GGO. CONCLUSION Our study concludes pure GGOs, though lacking solid component have a high propensity to be malignant. The role of repeated CT surveillance in this context without offering curative surgery may be questionable.

Abstract
Objective The aim of this study was to compare the radiological features of intravertebral clefts (IVC) between Kümmell disease (KD) and acute osteoporotic vertebral compression fracture (OVCF). Materials and Methods This is a retrospective study. A total of 79 patients with IVC from January 2014 to December 2018 were included in this study. There were 22 men and 57 women, with an average of 73.5 years. Based on the exact time interval from injury to treatment and the pathological examination results, the patients were divided into KD group (44 patients) and acute OVCF group (35 patients). The two groups were compared by the margin sclerosis of IVC, vertebra and pedicle ossification, stress fracture of the spinous process, paravertebral callus, the shape of IVC, cleft in the adjacent disc, and flatness of IVC's margin from plain radiographs and computed tomography (CT). The two groups were compared by the IVC content, double‐line sign, and signal of fracture vertebral from their magnetic resonance imaging (MRI). Results There were no significant differences in sex, age, and fracture distribution between the KD group and the acute OVCF group. IVC was present in both the KD group and the acute OVCF group. Six radiological features were only present in the KD group, including sclerosis of the cleft margin (95.5%, 42/44), ossification of the fractured vertebrae (100%, 44/44), ossification of the pedicle (31.8%, 14/44), double‐line sign (27.3%, 12/44), stress fracture of the spinous process (13.6%, 6/44), and even formation of paravertebral callus (18.2%, 8/44). Although there were statistical differences in the other four radiological features of content of IVC (P = 0.02), cleft sign in adjacent intervertebral disc (P < 0.01), margin of IVC (P = 0.02), and the shape of IVC (P = 0.01) between the KD group and acute OVCF group, these characteristics could be found in both groups. Conclusion IVC could present in patients with both KD and acute OVCF; however, we found that marginal cleft sclerosis, vertebral and pedicle ossification, double‐line sign, spinous process fracture, and formation of paravertebral callus are unique radiological features of KD and could be used for differentiation of KD from acute OVCF with IVC.

Abstract
PURPOSE To describe the urological manifestations of Erdheim-Chester disease (ECD) and their computed tomography (CT) findings. METHODS We retrospectively reviewed 48 patients diagnosed with ECD at Peking Union Medical College Hospital from January 2014 to January 2020. Twenty-four patients exhibited urological manifestations. Their CT findings, including appearances of the involved area (e.g., perirenal space, renal sinus, ureters, renal arteries, and adrenal glands), occurrence rate of ECD involvement in each area, signal enhancement pattern after CT contrast agent administration, disease progression, and causes of hydronephrosis were discussed. RESULTS In 24 patients with evidence of ECD urological involvement, the most common manifestation was perirenal infiltration, appearing as "hairy kidney" on unenhanced CT scans and moderate signal enhancement on enhanced CT scans (17/24, 70.8%). Other manifestations included renal sinus infiltration (16/24, 66.7%), proximal ureter involvement (14, 58.3%), renal artery sheath (10, 41.7%), hydronephrosis (14, 58.3%), and adrenal glands involvement (8, 33.3%). The histiocytic infiltrate was mostly bilateral, starting from the perirenal space and spreading to the renal sinus and ureters. Hydronephrosis was usually associated with infiltration of ureters. CONCLUSION Kidneys are the most common visceral organs affected by ECD. CT scanning is not only advantageous in early diagnosis, but also critical for designing the treatment regime for patients with ECD.

Abstract
INTRODUCTION Tubercular bacterial meningitis continues to be an important cause of morbidity (especially neurologic handicap) in children from resource-poor countries. The present study was planned to assess the clinical and radiological presentation in cases of tubercular meningitis as well as to study the factors associated with mortality. METHODOLOGY This study was done over a period of 12 months on children between 5 years and 13 years with suspected TBM. Staging of tubercular meningitis was done according to RNTCP Pediatric TB guideline 2019. RESULT The study was conducted on a total of 47 pediatric patients with TBM. Mean age of children in present study was 8.77 ± 2.5 years. Our study documented male preponderance for TBM. Severe thinness was observed in 38.3% patients with TBM. Only 59.6% patients were immunized against tuberculosis and history of contact was documented in 40.5% patients. Maximum children belonged to stage I of TBM (59.6%) followed by stage III and stage II in 34% and 6.4% patients respectively. Montoux test positivity was observed in 14.9% patients only. CSF CBNAAT was positive in 6.4% patients. The most common finding was meningeal enhancement seen in 27.7% of patients followed by tuberculomas in 10.6%.Chest X ray was abnormal in 44.7% patients. In present study mortality was observed in 11 (23.4%) cases. Out of various risk factors, mortality was significantly associated with nutritional status and stage of TBM (p < 0.01). CONCLUSION TBM is associated with high morbidity and mortality in children especially in India where Burden of TB is high. Our study emphasized on the risk factors associated with mortality in children with TBM and need for early diagnosis and appropriate treatment.

Abstract
Coronavirus disease-19 (COVID-19) is only one of the many possible infectious and non-infectious diseases that may occur with similar imaging features in patients undergoing [18F]-fluorodeoxyglucose (18FDG) monitoring, particularly in the most fragile oncologic patients. We briefly summarise some key radiological elements of differential diagnosis of interstitial lung diseases which, in our opinion, could be extremely useful for physicians reporting 18FDG PET/CT scans, not only during the COVID-19 pandemic, but also for their normal routine activity.

Abstract
In mid-December 2019, a novel atypical pneumonia broke out in Wuhan, Hubei Province, China and was caused by a newly identified coronavirus, initially termed 2019 Novel Coronavirus and subsequently severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of 19 May 2020, a total of 4,731,458 individuals were reported as infected with SARS-CoV-2 among 213 countries, areas or territories with recorded cases, and the overall case-fatality rate was 6.6% (316,169 deaths among 4,731,458 recorded cases), according to the World Health Organization. Studies have shown that SARS-CoV-2 is notably similar to (severe acute respiratory syndrome coronavirus) SARS-CoV that emerged in 2002–2003 and Middle East respiratory syndrome coronavirus (MERS-CoV) that spread during 2012, and these viruses all contributed to global pandemics. The ability of SARS-CoV-2 to rapidly spread a pneumonia-like disease from Hubei Province, China, throughout the world has provoked widespread concern. The main symptoms of coronavirus disease 2019 (COVID-19) include fever, cough, myalgia, fatigue and lower respiratory signs. At present, nucleic acid tests are widely recommended as the optimal method for detecting SARS-CoV-2. However, obstacles remain, including the global shortage of testing kits and the presentation of false negatives. Experts suggest that almost everyone in China is susceptible to SARS-CoV-2 infection, and to date, there are no effective treatments. In light of the references published, this review demonstrates the biological features, spread, diagnosis and treatment of SARS-CoV-2 as a whole and aims to analyse the similarities and differences among SARS-CoV-2, SARS-CoV and MERS-CoV to provide new ideas and suggestions for prevention, diagnosis and clinical treatment.

Abstract
PURPOSE To identify differences in the radiological findings of invasive pulmonary aspergillosis (IPA) among patients classified by severity of neutropenia, and differences in underlying disease. MATERIALS AND METHODS We retrospectively reviewed computed tomography (CT) scans from the time of the diagnosis of IPA in 83 hematological malignancy patients with probable or proven IPA according to the EORTC-MSG criteria. We evaluated CT findings (radiological pattern, number of lesions, distribution, and presence of low attenuation area [LAA]), and compared the radiological findings of patients classified by degree of neutropenia with two different indicators (neutrophil count at the onset, and c-d-index) and underlying disease. RESULTS Neutropenia at the onset of IPA was associated with an increased frequency of LAA (p < 0.05), especially in FN (p < 0.01). Cases with a c-d-index of ≧5500 showed an increased incidence of the angio-invasive pattern. In contrast, cases with a c-d-index of 0 showed an increased incidence of the airway-invasive pattern (p < 0.05). The airway-invasive pattern was more frequent in cases with MM, while the angio-invasive pattern was more frequent in cases with AML (p < 0.01). Lower-predominant distribution was more frequent and random distribution was less frequent in cases with AML, random distribution was more frequent and lower-predominant distribution was less frequent in cases with ALL, and upper-predominant distribution was more frequent in cases with MDS (p < 0.05). CONCLUSIONS CT features of IPA vary according to the degree of neutropenia and underlying disease.

Abstract
BACKGROUND Sarcomatoid intrahepatic cholangiocarcinoma (SICC) is an extremely rare and highly invasive malignant tumor of the liver. To our knowledge, the imaging findings of sarcomatous cholangiocarcinoma have been rarely reported; and radiological features of this tumor mimicking liver abscess have not yet been reported.
CASE SUMMARY We present a case of SICC mimicking liver abscess. The patient, a 43-year-old male, complained of repeated upper right abdominal discomfort and intermittent distension over a period of one month. Radiology examination revealed a huge focal lesion in the right liver. The lesion was hypointense on computed tomography with honeycomb enhancement surrounded by enhanced peripheral areas. It showed a hypo-signal on non-contrast T1-weighted images and a hyper-signal on non-contrast T2-weighted images. Radiologists diagnosed the lesion as an atypical liver abscess. The patient underwent a hepatectomy. After surgery, he survived another 2.5 mo before passing away. A search of PubMed and Google revealed 43 non-repeated cases of SICC reported in 20 published studies. The following is a short review in order to improve the diagnostic and therapeutic skills in cases of SICC.
CONCLUSION This report presents the clinical and radiological features of SICC and imaging features which showed hypovascularity and progressive enhancement. SICC can present as a multilocular cyst on radiological images and it is necessary to distinguish this lesion from an atypical abscess. Simple surgical treatment is not the best treatment option for this disease.

Abstract
The most conspicuous element of Gorham's disease is its radiographic features, wherein massive disappearance of the mandible is observed. We report a case of an adolescent boy with massive osteolysis of the mandible in whom the diagnosis of Gorham's disease was made. A 14-year-old boy was referred to the Department of Oral and Maxillofacial Surgery, Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, for the management of a massive mandibular deformity. He was diagnosed with a hemangioma-like lesion at 1 year of age. The disease had progressed for an unknown number of years. Plain X-rays and computed tomography images were examined for reconstructive surgery planning. Gorham's disease is self-limiting, but has catastrophic results. The role of imaging is huge, particularly for reconstructive surgery planning.

Abstract
The radiological features of lower-grade gliomas (LGGs) classified according to isocitrate dehydrogenase (IDH) mutations and codeletion of chromosomal arms 1p and 19q (1p/19q codeletion) remain unclear. We aimed to systematically characterize the radiological features of molecularly classified LGGs using IDH and 1p/19q codeletion statuses. One hundred and one LGGs were re-classified into 36 tumors with IDH mutations (IDH-Mut), 35 tumors with IDH-Mut and 1p/19q codeletion (IDH-Mut/Codel), and 30 tumors with wildtype IDH (IDH-Wt). Calcification, heterogeneous signal intensity in T2-weighted images, and cortical invasion were significantly more frequent in IDH-Mut/Codel than in IDH-Mut and IDH-Wt tumors (calcification: 48.6 vs 5.6 and 6.7%, heterogeneity: 94.3 vs 33.3 and 50%, and cortical invasion: 94.3 vs 55.6 and 40.0%, respectively). A frontal location was significantly more frequent for IDH-Mut and IDH-Mut/Codel than for IDH-Wt tumors (52.8 and 71.4 vs 12.1%, respectively), and dense contrast-enhancement was significantly more frequent in IDH-Wt than in IDH-Mut and IDH-Mut/Codel tumors (50.0 vs 2.8 and 2.9%, respectively). In conclusion, IDH-Mut/Codel tumors were characterized by calcification, frontal location, heterogeneous signal intensity, and cortical invasion; IDH-Mut tumors differed from IDH-Wt tumors according to predominant frontal lobe location and less frequent dense enhancement patterns.

Abstract
BACKGROUND Human papillomavirus (HPV)-driven oropharyngeal squamous cell carcinoma (OPSCC) represents a distinct tumour entity in comparison to HPV-negative OPSCC. The clinical, radiological, morphological features and distribution of HPV E6/E7 mRNA were investigated in resected specimens of OPSCC. METHODS We retrieved formalin-fixed, paraffin-embedded whole section slides from 24 p16/HPV-DNA positive and 18 p16/HPV-DNA negative primary tumours and 16 corresponding metastases in patients with early-stage OPSCC who underwent planned curative or diagnostic primary transoral robotic surgery. A detailed clinicoradiological and histopathological investigation of the tumours was performed along with detection of HPV E6/E7 mRNA by in situ hybridisation. RESULTS HPV-driven OPSCC was characterised by non-keratinising morphology and was dominated by a cohesive invasion pattern at the leading edge of the tumour. Dysplastic zones of the squamous epithelium were strictly located in the tonsillar crypts in contrast to HPV-negative OPSCC which predominantly arised from the dysplastic surface epithelium. Thirteen HPV-driven OPSCC invaded through the tonsillar lymphoid compartment and into soft tissue, causing a stromal desmoplastic reaction. HPV mRNA was consistently but inhomogenously expressed in the entire tumour area and in the dysplastic squamous epithelium. There was no HPV expression in the adjacent normal epithelium and in the non-neoplastic tissues. CONCLUSIONS This study enhances the current understanding of HPV-driven OPSCC. Only tumours that invade through the lymphoid compartment induce a stromal desmoplastic reaction. A consistent but inhomogenous expression of E6 and E7 mRNA was found in tumour and dysplastic areas, emphasizing that the E6/E7 oncogenes are the driving factors in HPV-driven OPSCC.

Clinical and radiological features driving patient selection for antiangiogenic therapy in non-small cell lung cancer (NSCLC). Cancer Imaging 2016; 16:44.

Abstract
BACKGROUND The use of antiangiogenic therapy in non-small cell lung cancer (NSCLC) requires thorough evaluation of patient characteristics in order to avoid potential safety issues, particularly pulmonary haemorrhage (PH). The aim of this consensus by a panel of experts was to identify important criteria for the selection of patients with NSCLC who would benefit from antiangiogenic therapy. METHODS Radiologists and oncologists were selected for the expert panel. The nominal group technique (NGT) and the Delphi questionnaire were used for consensus generation. The NGT consisted of four steps, the result of which was used to set the Delphi questionnaire. A final report was generated based on the opinions of the experts from the panel. RESULTS An extremely important prerequisite for the evaluation of an antiangiogenic therapeutic approach in patients with NSCLC was thorough clinical and radiological analysis of the relationships between tumour and vascular or anatomical structures (performed in close co-operation by oncologists and radiologists). The panel identified major parameters to be considered before the use of antiangiogenic treatment, collectively agreeing on the relevance of tumour cavitation, vascular infiltration, endobronchial growth and thromboembolism for chest tumour sites, and of the presence of aneurysms, extra-thoracic bleeding, brain metastases or thrombi for extra-thoracic sites. Moreover, a structured report containing information not only on the tumour but also on the general vascular status is essential to guide the treatment choice The experts agreed that tumour localization in the absence of vessel infiltration, cavitation, and the use of antiplatelet therapy are relevant parameters to be assessed, but their presence should not necessarily exclude a patient from receiving antiangiogenic therapy. CONCLUSION Close co-operation between oncologists and radiologists in the diagnosis, treatment selection, and assessment of response is essential for ensuring therapeutic appropriateness in the NSCLC setting. It should be noted that neither the use of antiplatelet therapy nor tumour localisation are to be considered as contraindications to antiangiogenic treatment.

Abstract
INTRODUCTION A rare case of vagal paraganglioma is reported. MATERIAL AND METHODS The specific radiological features of this tumor are presented to the clinician in order to make presumptive diagnosis. CONCLUSION By CT-scan and/or MRI it must be suspected when a hypervascular tumor in relation to the major cervical vessels displaces the internal and external carotid arteries forward, does not open the carotid bifurcation, and displaces the internal jugular vein backwards.

Abstract
OBJECTIVE To elucidate the clinico-radiological features, treatment response and outcome of a large cohort of patients (n=20) with idiopathic hypertrophic pachymeningitis (IHP) and to examine if any of these features could differentiate between IHP and secondary causes of hypertrophic pachymeningitis (SHP). METHODS 20 patients with IHP diagnosed between 1998 and 2009 formed the study cohort. We adopted a validated clinical score to quantitatively assess and document their neurological disability and to compare their pre- and post-treatment outcomes. Appropriate statistical analysis was done to look for any clinical and/or radiological features to differentiate IHP from SHP. RESULTS Out of the twenty eight consecutive patients with pachymeningitis, 20 were having IHP and 8 were having SHP (Tuberculosis-5, Sarcoidosis-2, Wegener's granulomatosis-1). In IHP, headache and visual symptoms dominated the clinical symptomatology (80% and 75%). In MRI, the peripheral pattern of contrast enhancement was more common with IHP (p=0.03). The posterior falx and tentorium showing a hypointense center ("fibrosis") and enhancing periphery ("active inflammation") together mimicking "Eiffel-by-night" sign was found to be more commonly associated with IHP (60% vs 12.5%, p=0.03). Biopsy was done in 9 patients. At a mean follow-up of 51 months (range 24-144 months), the mean pretreatment clinical score improved from 6.55 to 1.80 in 20 patients with IHP (p<0.001). CONCLUSIONS Our data on the largest cohort of patients with IHP would shed light into its clinico-radiological spectrum, treatment and outcome. The prognosis is satisfactory if managed appropriately. We have highlighted the role of MRI in differentiating between IHP and other causes of SHP.

Abstract
From 1997 to 2013, 8849 patients with several disorders of the thyroid were treated in our surgical department. In nine patients (0.1%), primary thyroid sarcoma (PTS) was diagnosed. In eight patients, PTS manifested as a thyroid mass (range, 25-90 mm). In one case, a global enlargement of the thyroid was seen. Clinically, all patients presented with neck swelling. On ultrasound, PTS was predominantly hypoechoic. On computed tomography, the sarcomas were hypodense. On magnetic resonance imaging, PTS had inhomogeneous signal increase on T2-weighted images and signal decrease on T1-weighted images with inhomogeneous enhancement.

Abstract
BACKGROUND Congential diaphragmatic herniae pose serious challenges in their management in this environment.Aim & Objective: To determine the pattern, as well as the diagnostic and management challenges of congenital diaphragmatic hernia in Dakar, Senegal. PATIENTS AND METHODS This is a retrospective review of 14 children with congenital diaphragmatic hernia (CDH) managed within eleven years in Dakar, Senegal. RESULTS There were nine boys and five girls with the age range of one day to 22 months and a mean of 5 months. Respiratory signs (respiratory distress, cough, current pulmonary infection) were found in 13 patients and gastrointestinal symptoms (vomiting, Difficulty sucking, anorexia) in 6 patients. The thoracic-abdominal radiography was performed in all patients and revealed a Bochdalek hernia on the left in 10(71%) cases and 4(29%) were Morgagni hernia. Treatment was by repair of the diaphragmatic defect with non-absorbable sutures. The postoperative course was uneventful in 13 children while one patient died on the first postoperative day one. CONCLUSION Congenital diaphragmatic hernia presents mainly with postnatal respiratory features in this setting. Thoracic-abdominal radiography allows for early diagnosis, prompt and effective treatment with good outcome.
