Abstract
- The sudden onset of involuntary movement is usually attributed to a vascular lesion in the contralateral deep hemispheric structure. A majority of involuntary movement cases record that all the limbs on one side are affected. The concurrence of venous and cavernous malformations may be relatively rare, but is important because of the possibility of bleeding which should be related to the presence of cavernous angioma. A 67-year-old woman was admitted to our hospital to be evaluated for choreic movement restricted to the right leg for 20 days. A brain MRI revealed hemorrhage with the cavernous angioma involving the left striatum and adjacent venous angioma. Haloperidol diminished the monochoreic movement. We report monochoreic movement restricted to the right leg due to a left striatal lesion.
