The patient, a 66-year-old woman, underwent routine cardiological assessment before chemotherapy for newly diagnosed breast cancer and was found to have a mass in the right atrium. She was entirely asymptomatic. A port had been implanted two weeks earlier. Transesophageal echocardiography (Figures a and b) and cardiac MRI and CT scans revealed a mass, 39 x 23 mm in size, on the lateral wall of the right atrium below the ostium of the inferior vena cava. Contact to the tricuspid valve and the port system could not be excluded. A number of possible diagnoses were considered, including a thrombus associated with the port system, a primary tumor, and a metastasis; each of these would have called for a different clinical management. Surgical resection was recommended as the next step by interdisciplinary consensus. Histological examination revealed an atrial myxoma with regressive changes.
