Abstract

A case of bilateral dilatation of the internal auditory canal without acoustic tumors, which was the so-called patulous internal auditory canal, is reported. The patient was a 12-year-old boy with bilateral sensorineural hearing loss, canal paresis in the left ear, anal atresia, epilepsy, mental retardation, and A-V block.<br>Radiographs showed that the maximum diameter of the internal auditory canal was 12.8 mm on the left and 16.3 mm on the right. CT and MRI showed no evidence of an intracanalicular mass. Diffusion-weighted imaging was useful for a definitive diagnosis. No epidermoid cyst was present in the internal auditory canal.
