title: Intracranial leiomyosarcoma in a patient with AIDS.
abstract: We report an intracranial leiomyosarcoma in the pontine cistern of a 34-year-old woman infected with the human immunodeficiency virus (HIV). The clinical, radiological and pathological data are reviewed. The tumor was Epstein-Barr virus (EBV) positive by in situ hybridization. This case emphasizes that smooth muscle neoplasms arising in the setting of immunocompromise can occur intracranially, and corroborates a hypothesis that EBV coinfection may have a role in development of these tumors.
