Coexistence of an intracerebral vascular malformation and a brain tumor is an infrequent occurrence. Seven such cases have been reported in the literatures. We report a case of coexistence of arteriovenous malformation and pleomorphic xanthoastrocytoma. A 29-year-old woman was admitted with presentation of headache for 20 days. MR images showed an intra-axial mass in the right lateral ventricle, which was coexisted with arteriovenous malformation in the right frontal region. Pathological findings indicated that the intracranial mass was pleomorphic xanthoastrocytoma. This case raises several questions about plausible pathogenesis for coexistence of arteriovenous malformation and pleomorphic xanthoastrocytoma: that is, the coexistence of two separate lesions, the evolution of one lesion into the other. The authors report an unusual case of pleomorphic xanthoastrocytoma coexisted with arteriovenous malformation with review of literatures.
Key Words: Arteriovenous malformation; Pleomorphic xanthoastrocytoma
