Transesophageal Echocardiographic Detection of Malignant Lymphoma.

Transesophageal echocardiography (TEE) is an excellent method for visualizing pathology of the mediastinum. We present a case in which TEE detected an unsuspected lymphoma posterior to the descending thoracic aorta in a man suspected of having endocarditis. This case illustrates the advantages of TEE over transthoracic echocardiography in examining the mediastinum and the importance of performing a complete TEE examination.
