Left hemiparesis from atrial myxoma emboli.

Atrial Myxomas are benign primary tumors of the heart, arising mainly from the left atrium. Clinical signs and symptoms produced by atrial myxomas may be non-specific or result in mechanical obstruction of cardiac function, arrhythmias, and embolization. The authors present a case of a 60-year-old woman who developed total left hemiparesis resulting from left atrial myxoma embolization causing complete occlusion of the right middle cerebral artery.
