Abstract
Pleomorphic xanthoastrocytomas (PXA) are rare tumors of glial origin comprising <1% of all astrocytic tumors of brain. These are rare in the infratentorial compartment and have not known to arise from middle cerebellar peduncle till date. The authors here discuss a case of a 16 year boy who presented in an altered sensorium and features of raised intracranial pressure and was found to have a 4 x 4 x 3 cms mass arising from the middle cerebellar peduncle. The authors also discuss the histopathological features of these tumors suggesting their resemblance to other mal-developmental tumors, the rarity of pure WHO grade II PXA in infratentorial compartment, as well as the appropriate management.
