Facial nerve decompression of a PICA vessel loop: A case report.

ABSTRACT:

Introduction and importance

Facial nerve palsy is a common condition with various etiologies. However, compression due to a vessel loop is an exceptionally rare cause. This case report highlights the unusual presentation and management of facial nerve palsy caused by vascular compression, emphasizing the importance of considering rare etiologies in persistent cases.

Case presentation

We describe the case of a young female patient who presented with a history of right blepharospasm and facial muscle twitching for several years. Cranial magnetic resonance imaging (MRI) revealed a posterior inferior cerebellar artery (PICA) vessel loop compressing the exit of the acoustofacial bundle at the level of the brainstem.
