Hearing loss associated with progressive ataxia (Lichtenstein-Knorr disease?). Report of a sporadic case with peculiar neuroradiological findings.

ABSTRACT

A sporadic case of hearing loss with ataxia, clinically suggesting Lichtenstein-Knorr disease, is described. Magnetic Resonance (MR) shows an involvement of the white matter, which appears diffusely reduced and abnormal, together with a peculiar tickening of the grey matter. The possible relationships with leukodystrophies and with generalized cortical dysplasias are discussed. To our knowledge, MR imaging has never been performed in Lichtenstein-Knorr disease.
