Résumé
Acquired hepatocerebral degeneration also termed acquired hepatolenticular degeneration, cirrhosis-related Parkinsonism o pseudo-Wilson is a rare, progressive and chronic neurological syndrome that occurs in patients with chronic liver disease, particularly in those with surgically or spontaneously induced portosystemic shunts. The clinical features of this pathological entity include extrapyramidal signs, ataxia, cognitive decline and neuropsychiatric changes, such as delirium, apathy, lethargy and emotional instability. Brain Magnetic Resonance Imaging classically shows symmetrical T1-weighted hyperintensities in the globus pallidus, substantia nigra and periaqueductal gray matter. Although its pathogenesis is not completely elucidated, it is postulated that the excess manganese accumulation and deposition in the basal ganglia, leading to dysfunctional dopaminergic system in this anatomical location, would have a key role in triggering the disease. Orthotopic liver transplantation is the mainstay of treatment and is considered effective by reducing motor and cognitive alterations. Other therapeutic alternatives that have reported symptomatic improvement are the use of bromocriptine or levodopa and portosystemic shunts occlusion. In this article, we report a case of a 63-year-old woman with clinical manifestations over the course of one year, characterized by cognitive decline, chorea, gait and language disturbances. She was examined with plasma levels of copper and ceruloplasmin, which excluded the possibility of Wilson´s Disease, its main differential diagnosis. Neuroimaging revealed T1-weighted hyperintensity in the pallidum, confirming suspected diagnosis of acquired hepatocerebral degeneration.
