A Case of Pleomorphic Xanthoastrocytoma

A case of pleomorphic xanthoastrocytoma of the temporal lobe in a 27 year-old man who had severe frontal headache and diplopia is presented. Brain computed tomographic scan revealed a relatively wel demarcated, slightly hyperdense mass with cyst surrounding low density in left temporoparietal area. After contrast enhancement, the mass was totally removed. Despite of their highly pleomorphic and bizzarre cytology, which suggests a malignant behavior, these tumors appear to have a relatively favorable prognosis.
