Infratentorial angioleiomyoma: a new location for a rare neoplastic entity.

Abstract

Angioleiomyomas are benign neoplasms most often located in the subcutaneous tissue of middle-aged individuals and usually confined to the subcuticular and deep dermal layers of the lower extremities. An intracranial site for this tumor is exceedingly rare, with very few reports documenting locations in the neuraxis. To the authors' knowledge the present case represents the first reported instance of an infratentorial angioleiomyoma. The authors conducted a review of selected English-language papers published since 1960 describing well-documented cases of intracranial vascular leiomyomas, with detailed information on the clinical presentation, radiology, pathology, and particulars of surgical management in each case.
