title: Pleomorphic xanthoastrocytoma with invasion of the tentorium and falx.
abstract: A case of a 21-year-old patient with a recurrent pleomorphic xanthoastrocytoma with invasion of the tentorium and falx cerebri is reported. Dural attachment has been reported in some cases. Invasion of the dura of the falx cerebri and complete infiltration of the left tentorium by the tumor were found intraoperatively. This is the first case in the literature which shows invasion of the dura in a pleomorphic xanthoastrocytoma.
