Abstract
We present a case of pleomorphic xanthoastrocytoma (PXA) in a patient with temporal lobe seizures. Imaging sequences included MR, and results of positron emission tomography (PET) with [18F]-fluorodeoxyglucose (FDG) and [11C]-methionine (Met) tracers revealed a hypermetabolic region equivalent or nearly equivalent to normal cerebral cortex, suggesting that the tumor might have malignant potential. Histopathologic findings indicated low-grade glioma. The mechanism for glucose hypermetabolic activity of PXA is not clear; however, the positive findings obtained from FDG-PET may not always indicate the degree of malignancy associated with PXA.Entities:
