Pleomorphic xanthoastrocytoma

Discussion:

Pleomorphic xanthoastrocytomas (PXA) are a type of rare, low-grade astrocytoma (WHO Grade II) found in young patients who typically present with temporal lobe epilepsy, as in this case. 

They are commonly characterized as cortical tumors with a cystic component and vivid contrast enhancement. Differentials would include ganglioglioma (can look very similar) and dysembryoplastic neuroepithelial tumors (DNET).
