Angioleiomyoma of the internal auditory canal: clinical and radiographic features.
OBJECTIVE
Discussion of a rare case of angioleiomyoma of the internal auditory canal.


METHODS
Thirteen-year-old female patient with a 1-year history of progressive hearing loss.


METHODS
Middle cranial fossa approach providing complete surgical extirpation.


METHODS
Surgical pathology.


RESULTS
Radiography and history suggestive of vestibular schwannoma; pathology revealed angioleiomyoma.


CONCLUSIONS
Angioleiomyoma is a rare lesion of the internal auditory canal that has many similar clinical and radiographic features of a vestibular schwannoma. There are no previous reports of this tumor occurring within the internal auditory canal in this age group.
