Abstract
- We report a case of moyamoya disease in a 7-year-old boy whose initial manifestation was the sudden onset of right hemichoreoathetosis for one week. Magnetic resonance imaging demonstrated a small infarction in the left frontal subcortical white matter. Single photon emission computed tomography (SPECT) revealed a perfusion defect in the same region. Combined superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis and encephalo-duro-arterio-myo-synangiosis (EDAMS) were performed and his symptoms disappeared after surgery. SPECT also normalized after revascularization. Hemichoreoathetosis is a rare initial manifestation of moyamoya disaese and direct and indirect anastomosis is effective treatment of this rare symptom.
