[Chronic acquired hepatocerebral degeneration: the role of manganese and treatment by endovascular occlusion of a porto-systemic shunt].

This case report describes a 74 year-old woman with cirrhosis who developed choreo-athetotic movements associated with elevated whole blood manganese and symmetric hyperintense pallidum on T1-weighted magnetic resonance imaging. The diagnosis was chronic acquired hepatocerebral degeneration. The endovascular occlusion of portal-systemic shunts was temporarily effective.
