Rotatory vertebral artery syndrome (RVAS) is characterized by recurrent attacks of vertigo, nystagmus, and syncope induced by compression of the vertebral artery during head rotation. A 60-year-old man with atlas vertebrae fracture presented recurrent attacks of positional vertigo. Left-beat, upbeat and count clock-wise torsional nystagmus occurred after lying down and bilateral head roll (HR) showing no latency or fatigue. Magnetic resonance imaging revealed foramen magnum stenosis (FMS) and dominancy of right vertebral artery (VA). The flow of the right VA on transcranial Doppler decreased significantly during left HR. The slower the velocity was, the more the nystagmus was aggravated. RVAS can be evoked by FMS causing compression of the VA. And the nystagmus might be aggravated according to the blood flow insufficiency.

Abstract PDF Supplementary Material: Vestibular Paroxysmia and facial spasm may be caused by vascular compression of the vestibular and facial root entry zone. We report a case of paroxysmal nystagmus accompanied by facial spasm and which is well visualized by three-dimensional reconstruction images. The 3-dimensional reconstruction image supports the view that vestibular paroxysmia may occur with hemifacial spasm simultaneously due to vascular compression.
