Abstract
MRI gains greater importance in the differential diagnosis of retrocochlear hearing loss. Retrocochlear anakusis is rarely caused by aplasia or atroph ia of the cochlear nerv. In the following we report about a five year old b oy suffering from unilateral deafness, where a strongly T2-weighted CISS-3D MRI sequence demonstrates a missing of the cochlear nerv on the deaf side.
