Dear Sirs,

Vertebral artery dissection (VAD) is the most common cause of ischemic stroke in young patients with an estimated incidence of 1 of 100,000 per year [1]. VAD is characterized by a mural hematoma, which leads to stenosis with a high embolic and thrombogenic potentials [2]. Since the anterior inferior cerebellar artery provides the blood supply to the central (brainstem and cerebellum) and peripheral (labyrinth) cochleovestibular pathways, patients with VAD associated with a cochleovestibular symptoms might present brainstem infarction and/or labyrinthine infarction caused by microembolism in the vertebrobasilar system [3, 4]. Recently, a radiological report demonstrated that 3D-FLAIR sequences performed 4 h after gadolinium administration might detect labyrinthine infarction due to the presence of a slight impairment of the blood–labyrinth barrier while 10 min post-contrast 3D-FLAIR showed no anomalies [5].

A 28-year-old female was referred to our tertiary neuro-otological...
