case_images: Contrast enhancement MRI of the internal auditory canal. The right AICA compressed the vestibulocochlear nerve. AICA, anterior inferior cerebellar artery; XIII, vestibulocochlear nerve.

case_images: VP according to the criteria proposed by the Barany Society in 2016 (Table 1) (Strupp et al.,). VP due to neurovascular compression syndrome was diagnosed after a magnetic resonance imaging (MRI) scan with contrast enhancement of the brain, which revealed that the right AICA was compressing the cisternal segment of the vestibulocochlear nerve (Figure 1).
case_images: Brain MRI. T2-weighted sequences showed no tumor or other lesions in the cerebello-pontine angle and brainstem.

case_images: The MRI did not identify tumors, such as acoustic neuroma and meningioma, in the cerebello-pontine angle or any other brainstem lesions (Figure 2).
case_images: DSA of the vertebral artery and basilar artery. (A) Frontal position of the RVA. (B) Lateral position of the RVA. (C) The LVA. The right vertebral artery was fenestrated, the right AICA was thick, and the left AICA was not visualized (A, B). The LVA terminated in the PICA (C). AICA, anterior inferior cerebellar artery; RVA, right vertebral artery; LVA, left vertebral artery.
