Cystic tumor in the left atrium: an unusual aspect of a myxoma.

: Most cardiac tumors are benign, whereas up to 50 % of the diagnosed cases are histologically myxomas. The common clinical signs are rhythm disturbances, myocardial ischemia, pulmonary edema, syncope and cardiac arrest. They do normally lead to the diagnostic hypothesis of an intracardiac mass. The primary modality for imaging is echocardiography which usually confirms the suspected diagnosis. But in rare cases there are masses which cannot be exactly identified by this technique. Here we present a patient with an atypical echocardiography of an unusual intracardiac tumor.
