Intimal sarcomas are rare malignant mesenchymal tumors that arise in the large arteries and rarely in the heart. Herein, we report the case of a 55-year-old man who was referred for further assessment of a right ventricular outflow tract mass. Assessment with cardiac magnetic resonance imaging revealed an enhancing mobile mass arising within the right ventricular outflow tract and extending into the main pulmonary artery. The initial diagnostic possibilities included thrombus and myxoma. The patient underwent surgical recession of the mass and the histopathology examination confirmed the diagnosis of cardiac intimal sarcoma.
