Unilateral chorea linked to cavernous haemangioma involving the putamen improved by surgery


Unilateral chorea movements caused by cavernous haemangioma in the putamen are extremely rare. We report a case with chorea movements linked to cavernous haemangioma, localised to an area including the putamen in which pharmacotherapy was found to be ineffective. Symptoms were, however, improved by resection of the cavernous haemangioma. In cases where chorea movements linked to cavernous haemangioma, involving the putamen, prove intractable with watchful waiting or pharmacotherapy, improvement can be expected with surgical removal of the cavernous haemangioma. It is also possible to reduce the risk of complications through the use of intraoperative navigation and monitoring.
