Right hemichorea treated successfully by surgical removal of a left putaminal cavernous angioma

Abstract

Rapid onset hemichorea corresponds usually to a structural esion located in the contralateral basal ganglia. Cavernous angioma CA) may be rarely a possible cause for acute appearance of this iskinesia [1–3]. We were able to find only one case description f hemichorea disappearance after microsurgical removal of CA ocated in the caudate nucleus at a child [2]. To the best of our nowledge, this is the first demonstration that hemichorea can e successfully treated by extirpation of CA localized also in the ontralateral putamen at an adult patient.
