Abstract:
PURPOSE: To draw attention to the radiological findings of a benign variant of cerebral astrocytoma in a young patient. MATERIALS AND METHODS: A 24-year-old man with generalized tonic-clonic seizure of 7 years' duration and normal neurological examination was examined with plain skull series, brain CT and MRI, and cerebral angiography. MR imaging was performed with a 0.5 Tesla Toshiba MRT-50A scanner (TIWI, PDWI, T2WI, 0.1 mmol/kg of Gd- DTPA, SE). RESULTS: 1 ) Plain skull series: A radiolucent lesion with a partial radiopaque rim of about 2.5 x 3 cm size in the right anterior parietal bone.2) B rain CT scan: A cystic mass in the right frontoparietal cortex of midconvexity with pressure erosion on the adjacent skull and partial enhancement at outer and anterior portion.3) Brain MRI:A hypointense mass containing a small, intensely enhancing isointensity anterolaterally on Tl-weighted images, which was hyperintense with better delineation of bulging cortical-based appearance on T2-weithted images. No peritumoral edema.4) Cerebral anglography: An avascular mass. CONCLUSION: The diagnosis of pleomorphic xanthoastrocytoma(PXA) should be entertained in patients in whom a superticially placed enhancing intracerebral tumor containing cystic portion that seems to be in contact with the meninges develops during juvenile years.
