Tentorial meningioma presenting as hemifacial spasm: An unusual clinical scenario.

Abstract

Hemifacial spasm (HFS), which is a rare clinical entity, occurs most commonly due to vascular structures at facial nerve root entry zone. Tumor as a cause of HFS is rarely described in the literature. Here, we describe an unusual case of HFS which is caused by contralateral tentorial meningioma. The pathology, etiology, and surgical treatment have been discussed.
