Bilateral Middle Cerebellar Peduncle Infarction Presenting With Vertigo and Hearing Impairment Mimicking Peripheral Vestibulopathy

Nur Amalina Ramli et al. Cureus. .

Abstract

Bilateral middle cerebellar peduncle (MCP) infarction is a rare manifestation of ischemic stroke. We report a middle-aged male patient who presented with acute onset of vertigo, left ear deafness, and severe ataxia. Magnetic resonance imaging (MRI) of the brain confirmed the presence of infarction in the bilateral middle cerebellar peduncles due to stenosis of the posterior circulation arteries. This case highlights the importance of recognizing this clinical syndrome, as the symptoms may resemble those of peripheral vestibulopathy. Timely recognition is of paramount importance, given that untreated posterior circulation stroke can result in poor neurological outcomes.

Keywords: acute hearing loss; aica infarct; middle cerebellar peduncle; stroke; vertigo.

Magnetic resonance angiography (MRA) shows inadequate visualization of the vertebrobasilar arteries (F), suggesting significant stenosis.
