Pleomorphic xanthroastrocytoma


Pleomorphic xanthoastrocytoma is probably the most likely diagnosis, the presentation is typical for age, location and appearance, note the hyperintensity of the cystic component relative to CSF seen on FLAIR denoting higher protein content.

Differential diagnosis includes other temporal lobe tumors such as ganglioneuroma, ganglioglioma or pilocytic astrocytoma.
