Cardiac myxoma

Three patients with left atrial myxoma presented with prominent neurologic symptoms and signs (cerebrovascular disease and/or syncope) within the past year. Two patients died because antemortem diagnosis was late or missed. One patient was successfully treated. Cardiac myxoma produces protean clinical manifestations that do not always include cardiac signs and symptoms. Neurologists may be called on for diagnostic consultation in patients who will prove to have cardiac myxoma. Unexplained transient ischemic attacks, cerebral infarction, or syncope (with possible features of seizure activity) are common neurologic manifestations of this disease. Additionally, systemic symptoms, signs, and laboratory data suggestive of collagen vascular disease or vasculitis are also often present. Echocardiography is a dependable noninvasive procedure for a confirmation of diagnosis in suspected cases.
