Serial changes of cranial computerized tomographic findings in Wilson disease during D-penicillamine therapy.

ABSTRACT

Serial changes of cranial CT findings were studied in three siblings with Wilson disease during the course of D-penicillamine therapy. The older two cases with neurological presentation revealed low density areas in the region of the basal ganglia on the CT scans performed before treatment. Mild cortical atrophy and mild enlargement of the lateral and the third ventricles were also observed. The chelating therapy resulted in a considerable improvement of neurological symptoms and disappearance of Kayser-Fleischer rings. The low density areas of the basal ganglia disappeared. However, cortical atrophy and an enlargement of the ventricles were still present. In an asymptomatic girl, the cranial CT scans remained normal after chelating therapy. The cranial CT scan is considered to be of great use both in diagnosis and observation of the clinical course in Wilson disease, and it is also of prognostic value.
