introduction: endoscopy is an invasive procedure and finding noninvasive alternative tools in detection of probable upper gastrointestinal (gi) tract injuries following caustic ingestion is an area of interest. the present study aimed to evaluate the screening performance characteristics of thoraco-abdominal computed tomography (ct) scan in this regard. methods: this prospective cross sectional...

FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...

The pineal gland is very important human endocrine gland and its location and size is very important for the neurologist and neurosurgeons and for the radiologist because in certain radiological investigations it is the guide of midline and its right or left shifting is highly suggestive of space occupying lesion in the brain. The aim of study was to find out the morphometric parameters of pine...

Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...

Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...

Epidural hematomas which are located at the vertex are rarely seen and form a small percentage of total epidural hematomas. Tearing in the superior sagittal sinus is the usual cause of an epidural hematoma located in the vertex. The clinical features of this entity are non-specific; hence, localization of the lesion is difficult. We report an adult who was hit by a motorcycle an...
