Primary cardiac lymphoma: echocardiographic characterization and successful resection.

We present a case of primary cardiac lymphoma in a patient with dyspnea and hypoxemia. Transesophageal echocardiography reveals a large right atrial mass and an atrial septal aneurysm with right-to-left shunting through a patent foramen ovale. The patient underwent resection and atrial reconstruction. Pathology was a B cell lymphoma with diffuse large cell histology. There was no evidence of extracardiac involvement, and the patient is well 3 months postoperatively with a normal transthoracic echocardiogram.
