Abstract
We report a patient with Neurovascular Compression Syndrome (NVC) who felt solo vertigo.
A 48-year-old male with a history of asthma, complained of vertigo without cochlear symptoms.
On brain MRI and MRA, he was found to have "dolichoectasia" in his left vertebral artery.
We suspected that dolichoectasia induced his vertigo, speculating that his left vertebral artery (VA) compressed his left vestibular nerve (VN).
Pre-operative examination of neurotology showed normal values except for VEMP (vestibular-evoked-myogenic-potentials).
In operation for microvascular decompression (MVD), we confirmed left VA and that the posterior-inferior cerebellar artery compressed his left inferior vestibular nerve. MVD was successfully performed.
Post-operative examination of neurotology showed all normal, including VEMP.
The diagnosis of NVC and the indication of MVD for NVC were decided carefully, and we confirmed that VEMP was very useful for the diagnosis of NVC.
