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