Bilateral Alien Hand Syndrome in Cerebrovascular Disease: CT, MR, CT Angiography, and 99mTc-HMPAO-SPECT Findings

ABSTRACTWe report a 65-year-old man with a right cerebral infarction that occurred 15 years ago and a residual left hemiparesis that began with progressive contralateral hemiparesis. During the hospitalization, the patient developed a bilateral alien hand syndrome. Urgent CT, MR, CT angiography, and brain perfusion SPECT were performed that revealed an old right cerebral infarction and a new ischemic lesion in left parietal lobe and adjacent brain territories.
