Cerebral gliosarcoma: prognostic factors

Abstract
The authors report their results in a retrospective study of 6 cases of gliosarcoma. In 3 cases gliosarcoma presented features similar to those of glioblastoma, both at CT scan and macroscopically; in the other 3 cases they resembled meningioma. Average survival varied considerably and was correlatable to the CT features of the lesion (14 months for glioblastoma, 7 for meningioma). It seems likely that patients who have gliosarcoma with CT features suggestive of meningioma may have prolonged survival.
