Multicentric intracranial smooth-muscle tumor in a woman with human immunodeficiency virus. Case report.

A 31-year-old woman with acquired immunodeficiency syndrome (AIDS) was found to harbor both a pulmonary smooth-muscle tumor and an intracranial extraaxial smooth-muscle tumor of the parasellar region. The frequency of smooth-muscle tumors (leiomyoma and leiomyosarcoma) has increased with AIDS, but much more so in children than in adults. Only nine cases of human immunodeficiency virus-related smooth-muscle tumors have been previously reported in adults, and only one of these was located intracranially.
