Abstract

Pleomorphic xanthoastrocytoma (PXA) is a rare astrocytic tumor that usually occurs in the superficial cerebral hemispheres of children and young adult and has a favorable prognosis. We report a case of a 14-year-old girl with a recent history of sciatica and ataxic gait. Pre- and post-contrast brain and spinal MRI revealed the presence of multiple solid lesions with a cystic component in the cerebellum and the spinal cord with a concomitant massive leptomeningeal involvement Histological and immunohistochemical findings were concordant with a final diagnosis of WHO grade II PXA. Even the biological indolent PXAs' behavior, this is the third report in the literature of such an unusual multicentric PXA with leptomeningeal dissemination.
