title: Pulmonary embolism due to the right atrial myxoma.
abstract: A 47-year-old man was admitted to the hospital with a pleuritic pain, dyspnea, nonproductive cough and low-grade fever. An ECG documented a sinus tachycardia with S1Q3T3 pattern and incomplete right bundle branch block, and lung scintigraphy showed multiple perfusion defects. The initial diagnosis was pulmonary embolism. Echocardiography, undertaken before application of the anticoagulant therapy because of hematological disturbances reflecting possible coagulopathy (elevated erythrocyte sedimentation rate, increased leukocyte count, decreased platelet count), revealed a large mobile tumor in the right atrium. Tumor was surgically removed, and histological findings was supported a diagnosis of the cardiac myxoma. The right cardiac myxoma should be considered in the differential diagnosis of pulmonary embolism, particularly in cases presented in conjunction with constitutional symptoms and/or hematological disturbances. In these patients echocardiography should be undertaken early to exclude the rare but treatable diseases of the right heart.
