Atrial myxoma is a benign cardiac tumor found most commonly in the left atrium. They mostly present with dyspnea, fatigue or palpitations. Previously undiagnosed left atrial myxoma presenting as stroke is extremely rare. Authors describe the case of a middle aged man with LA myxoma presenting with acute embolic stroke.

We report a case of a 34-year-old female with low-grade dyspnea on exertion despite markedly dilated left atrium (LA) on chest radiography which clouded our interpretation of the cause of enlarged cardiac silhouette. However, echocardiogram proved useful in demonstrating severe mitral stenosis and the giant LA.
