Cardiac myxomas are the most common benign tumours in adults, with an incidence of 0.5 cases per million people per year, 75% of myxomas occur in females, and 15 to 20% located in the right atrium. Because their clinical presentation is variable, they are known as "great simulators" of the cardiac nosology. The primary clinical manifestations reported include asthenia, weight loss, fever, palpitations, dyspnea, syncope, and a heart murmur. They can produce lethal complications such as the formation of emboli, which can migrate and cause pulmonary thromboembolism, deep vein thrombosis and arrhythmias. We report a case of a male patient admitted in the emergency room with acute abdominal syndrome in whom the diagnosis of right ventricular myxoma had been not identified until his symptoms progressed to cardiac failure; we discussed the clinical and imaging (MSCT, MRI, and transthoracic ultrasound) findings of this entity with a brief review of the literature.
