Hamartomas of the Cerebellopontine Angle and Internal Auditory Canal: Report of Two Cases

Hamartomas of the Cerebellopontine Angle and Internal Auditory Canal: Report of Two Cases Abstract Most mass lesions of the internal auditory canal and cerebellopontine angle are neoplastic, expansile, and eventually symptomatic. We report two cases of neurogenic hamartomas at these anatomic sites. In a patient with unrelated auditory or vestibular symptoms, such a developmental lesion might result in false-positive posterior fossa contrast results.

Abstract

Abstract Most mass lesions of the internal auditory canal and cerebellopontine angle are neoplastic, expansile, and eventually symptomatic. We report two cases of neurogenic hamartomas at these anatomic sites. In a patient with unrelated auditory or vestibular symptoms, such a developmental lesion might result in false-positive posterior fossa contrast results.
