Some intraventricular mass lesions have proven difficult to delineate, even with a contrast-enhanced CT scan. The combination of intrathecal contrast and CT scanning has been especially useful in studying the ventricles and subarachnoid spaces of both the brain and spinal cord . We report a case in which we instilled metrizamide directly into the body of the left lateral ventricle to show the e...

This study investigates the possible characteristic Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings of parapharyngeal Pleomorphic Adenoma (PA), which is rarely found, reported. We analysed 6 cases that had been diagnosed with nasopharyngeal PA and surgically treated in the last 6 y with both the symptoms of the patients and the characteristics of the tumours.

A 63-year-old man with epigastric pain was admitted to the surgery department. Abdominopelvic CT-scan showed a hypodense mass lesion in distal gast...
