Male, 71 years old, with asymmetric left sensorineural hearing loss. The IACs are normally sized and patent. No IAC or CP angle masses are present. The vestibular and cochlear nerves are normal bilaterally. No pathologic enhancement is seen. The fluid filled structures of the inner ears show normal morphology. The brainstem shows normal signal characteristics. On limited intracranial views, there is mild patchy white matter hyperintensity, a non-specific finding. Small hippocampal sulcus remnant cysts are present bilaterally.
Unremarkable evaluation of the IACs with no specific findings to account for the patient's symptoms.
