title: Gliosarcoma: an unusual cause of cerebral mass lesion in a patient with AIDS. A case report and review of the literature.
abstract: Malignant glioma is the most common primary brain neoplasm. Generally, gliomas are not included in the differential diagnosis of enhancing lesions of the central nervous system in patients infected by the human immunodeficiency virus. We report a case of gliosarcoma in a patient with AIDS presenting as a single cerebral lesion. Stereotactic brain biopsy was obtained and definitive histopathological diagnosis of gliosarcoma was made. A decline in the incidence of opportunistic infections associated with highly active antiretroviral therapy suggest the importance of early stereotactic biopsy to confirm the diagnosis of these neoplasms.
