Summary

What Researchers Did

Researchers reported on a 44-year-old man who presented with vertigo, tinnitus, and bilateral sudden sensorineural hearing loss, ultimately diagnosed with acute bilateral middle cerebellar peduncle infarction.

What They Found

A 44-year-old man presented with complete bilateral hearing loss, diagnosed as acute bilateral middle cerebellar peduncle infarction via MRI. Despite normal brainstem auditory evoked potential, otoacoustic emissions indicated binaural cochlear dysfunction, suggesting a peripheral cause. Following treatment, his hearing significantly improved, with pure-tone averages of 67 decibels (dB) on the right and 73 dB on the left at 3 months.

Canadian Relevance

This case report has no direct Canadian connection as it was conducted outside of Canada.

Study Limitations

As a single case report, the findings cannot be generalized to a broader patient population.
