Case of the Month Unilateral Hearing Loss

Unilateral Hearing Loss

History & Examination
30 y/o previously healthy female presents with a 1 year history of progressive left-sided hearing loss and tinnitus.

Her past medical history and surgical history are unremarkable.

Physical examination reveals difficulty with tandem gait and nystagmus, but no dysmetria.

A limited post-contrast study of the IAC and an audiogram are obtained.

Diagnostic Studies
Word recognition scores in the right ear is 100% at 55 dB and 84% at 75 dB

PTA
22 dB (air) and 18 dB (bone) –right
42 dB (air) and 32 dB (bone) – left

Summary -moderate to severe sensorineural hearing loss for the left ear

T1-Weighted with contrast

T2-BFFE

Lateral inferior cerebellar peduncle approach

4 patients (3 woman and 1 man) who had a symptomatic dorsolateral brainstem cavernous malformation with radiographic and clinical evidence of hemorrhage, underwent excision via a far lateral suboccipital craniotomy through the foramen of Luschka and with an incision in the cerebellar peduncle.On intraoperative examination, 2 of the 4 patients had hemosiderin staining on the surface of the peduncle. All lesions were completely excised and all patients had a good or excellent outcome (modified Rankin Scale scores of 0 or 1).

Case series of Deshmuk et al., illustrates that intrinsic lesions of the dorsolateral medulla can be safely removed laterally through the foramen of Luschka and the inferior cerebellar peduncle 1).
