초록
We report a patient with acute bilateral caudate nucleus infarctions. The patient had no past medical history except diabetes mellitus. He presented with sudden inability to comprehend or verbalize and right-sided hemiparesis, which resolved spontaneously within 2 hours after the onset. On initial computed-tomographic angiography, the A1 segment of the right anterior cerebral artery (ACA) was hypoplastic, and the right A2 segment was occluded. Follow-up magnetic resonance images revealed bilateral caudate head infarctions including bilateral anterior internal capsules with a larger lesion on the left, and recanalization of the right A2 segment. Paroxysmal atrial fibrillation was detected on 24-hour Holter monitoring. This rare type of cerebral infarction were thought to be caused by cardiac emboli which passed by common A1 segment of the left ACA.

Follow-up magnetic resonance images revealed bilateral caudate head infarctions including bilateral anterior internal capsules with a larger lesion on the left, and recanalization of the right A2 segment. Paroxysmal atrial fibrillation was detected on 24-hour Holter monitoring.
