title: Internal auditory canal enlargement in neurofibromatosis without acoustic neuroma.
abstract: Acoustic neuroma has always been reported to accompany neurofibromatosis in patients with enlargement of the internal auditory canal. The authors describe a case in which the internal auditory canal was enlarged but there was no tumor. This may represent a normal variant or a manifestation of the bony dysplasia of neurofibromatosis.
