title: Right Ventricular Outflow Tract Tumor Mimicking a Thrombus in the Main Pulmonary Artery.
abstract: Primary sarcomas of the pulmonary artery and right ventricle are rare, and their presentation is unusual in clinical practice; therefore, their diagnosis is often missed or delayed. The progression of the obstruction from the outflow tract of the right ventricle to the pulmonary artery resembles massive pulmonary embolism. We present a case of one of these tumors which mimicked transesophageal echocardiography (TEE), a massive pulmonary embolism. We conclude that TEE represents a noninvasive method of diagnosis and evaluation when the suspicion is massive pulmonary thromboembolism or a heart tumor.
