Abstract

Purpose

To discuss a novel diagnosis of post-surgical iatrogenic AICA vasospasm following eighth cranial nerve microvascular decompression as the most likely etiology for a lateral pontine infarct.

Observations

A 49-year-old male presented with tinnitus, vertigo, binocular and monocular diplopia following left occipital decompressive craniectomy and microvascular decompression of cranial nerve VIII. Magnetic resonance imaging demonstrated patent vasculature with evolution of a subacute infarct of the left lateral pons and middle cerebellar peduncle in the territory of the left AICA.

Conclusions

We report a unique case of lateral pontine infarction without vascular occlusion acutely following surgical microvascular decompression of CN VIII, most consistent with post-surgical AICA vasospasm. This case provides a clear example of vestibular and neuro-ophthalmic complications of CN VIII microvascular decompression.

期刊介绍： The American Journal of Ophthalmology Case Reports is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished case report manuscripts directed to ophthalmologists and visual science specialists. The cases shall be challenging and stimulating but shall also be presented in an educational format to engage the readers as if they are working alongside with the caring clinician scientists to manage the patients. Submissions shall be clear, concise, and well-documented reports. Brief reports and case series submissions on specific themes are also very welcome.
