title: [Hemifacial spasm caused by a dissecting aneurysm of the vertebral artery, and resulting in acute exacerbation].
abstract: The authors report a rare case of a symptomatic hemifacial spasm caused by a dissecting vertebral artery aneurysm and by an anterior inferior cerebellar artery(AICA). A 54-year-old man presented with left hemifacial spasm persisting for 5 years, and the spasm had undergone acute aggravation. Brain magnetic resonance imaging and digital subtraction angiography showed a vertebral artery dissecting aneurysm and an AICA compressing the root exit zone of the left facial nerve. Microvascular decompression of the facial nerve with proximal clipping of the vertebral artery dissecting aneurysm was successfully performed. The hemifacial spasm disappeared immediately after the surgery.
