Abstract

Neurovascular compression syndrome is generally caused by vascular compression at the root entry or exit zone of the corresponding cranial nerve. Trigeminal neuralgia is the most frequent syndrome, followed by hemifacial spasm. Despite ongoing debate in the literature, pulsatile tinnitus is also known to be a neurovascular compression syndrome resulting from vascular compression of the vestibulocochlear nerve. Combined manifestations of neurovascular compression symptoms are very rare. We report a case with a simultaneous manifestation of trigeminal neuralgia, hemifacial spasm, and pulsatile tinnitus as neurovascular compression syndrome with separate offending vessels. A 53-year-old female presented with lancinating pain in the left face, left hemifacial spasm, and ipsilateral pulsatile tinnitus for 2 years. Trigeminal neuralgia and hemifacial spasm were diagnosed after a neurological examination, imaging study, and electromyography. Microvascular decompression via a retrosigmoid approach for separate offenders, including the superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery was performed using Teflon sponges. The patient’s hemifacial spasm, pulsatile tinnitus, and hemifacial pain improved immediately after microvascular decompression.
