Left atrial myxomas presenting with right hand weakness.

A 63-year-old man with multiple left atrial myxomas presenting with right hand weakness is described. Two-dimensional echocardiography obtained during the evaluation for his stroke showed a large left atrial mass. At surgery, two separate left atrial myxomas were excised. Pathology confirmed the diagnosis. Although left atrial myxomas are uncommon, they should be included in the differential diagnosis of stroke, especially in patients who present without cardiovascular or cerebrovascular risk factors. The absence of cardiac symptoms and signs does not rule out a cardiac myxoma.
