A pair of two atrial myxomas mimic thrombus in left atrial appendage and cause ischemic stroke in a young adult: a case report

Stroke is one of the leading causes of mortality and disability and can be rarely caused by cardiac myxoma. Here, we report about a 56-year-old man who suffered from a stroke presented with acute dysarthria and left hemiparesis. Magnetic resonance imaging (MRI) of the brain revealed an acute stroke. Atrial fibrillation (AF) was assumed the cause of stroke. Because of contraindication to anticoagulation due to previous cerebral haemorrhage with rivaroxaban the patient was admitted to interventional occlusion of left atrial appendage. Echocardiography revealed two left atrial masses suggestive of atrial myxomas. The patient was transferred to remove the two myxomas operatively with simultaneous resection of left atrial appendage. Atrial myxomas should be considered as a possible differential diagnosis of cardioembolic stroke. They should be managed early to prevent recurrent strokes.
