[Wilson's disease with primary CNS manifestation--current status in diagnosis and therapy].
Five cases studied at our clinic are discussed and the literature reviewed with the aim of assessing the diagnostic value of various examination methods used for Wilson's disease and a modified diagnostic approach is suggested. CT and MRI are compared with regard to sensitivity, specificity and prognostic value. Almost regularly, MRI showed bilateral lesions in the basal ganglia in combination with structural changes in the brain stem. A pattern consisting of symmetrical lesions of the red nuclei, the periaqueductal grey region and, facultatively, the substantia nigra and the dentate nuclei was discovered and appeared almost pathognomonic. Follow-up studies revealed excellent reversibility of MRI changes by both penicillamine and trientine. Auditory evoked potentials showed the highest sensitivity and the best correlation with structural findings. Kayser-Fleischer corneal rings--a diagnostic requirement in the literature--were not found in all patients. The current state of therapy and therapy management is discussed on the basis of pathophysiological considerations. As possible complications of penicillamine administration the deterioration of the clinical condition after initiating therapy, and the risks associated with an abrupt termination of therapy are discussed in detail.
