Pleomorphic xanthoastrocytoma: report of two cases.

Two cases of pleomorphic xanthoastrocytoma are presented to draw attention to this relatively benign variant of glioma. The circumscribed tumors, each with a cystic component, were located superficially, one in the mesial right temporal lobe and one in the right temporoparietal region. The patients were aged 12 and 14 years, and it is now almost 7 years since the onset of symptoms in the 12-year-old boy. The optimal plan of management is discussed.
