| Abstract: | A 58‐year‐old male with a history of a soft tissue sarcoma in remission presented with a 2 weeks history of progressive dyspnea. Transthoracic echocardiography showed right ventricular dilation; right ventricular systolic pressure (RVSP) of 110 mm Hg, and a lobulated mass in the right ventricular outflow tract (RVOT) causing obstruction. Microbubble contrast was administered showing perfusion within the mass, which suggested malignancy. A CT pulmonary angiogram (CTPA) confirmed the presence of the mass in the RVOT without evidence of pulmonary embolism. This case demonstrates the importance of the multimodality imaging approach for the differential diagnosis of masses in the RVOT. |
