Abstract

A pontine intracranial hemorrhage (ICH) evokes several neurological symptoms, due to the various nuclei and nerve fibers; however, hearing loss from a pontine ICH is rare. We have experienced a non-traumatic pontine ICH patient, with hearing loss. A 43-year-old male patient had a massive pontine hemorrhage; his brain magnetic resonance imaging revealed the hemorrhage on the bilateral dorsal pons, with the involvement of the trapezoid body. Also, profound hearing loss on the pure-tone audiogram and abnormal brainstem auditory evoked potential were noticed. Fifty-two months of long-term follow-up did not reveal any definite improvement on the patient's hearing ability.
