Cardiac myxoma is a true intracardiac neoplasm, which is histologically benign but which on occasion may exhibit behavior suggestive of a true malignancy. It is the most common form of primary cardiac tumor, accounting for 50% of such neoplasms. Seventy-five percent of myxomas are found in the left atrium, typically arising from a stalk attached to the area of the foramen ovale. ⋯ Four cases with unusual manifestations are high-lighted in the text to illustrate the protean manifestations of this potentially curable illness. Non-invasive cardiac imaging is essential to establish the diagnosis and differentiate myxoma from the other more common illnesses it imitates. Echocardiography is highly accurate for its diagnosis, has proved invaluable for the management of these patients, and is the imaging technique of choice for initial evaluation of patients in whom the diagnosis of cardiac myxoma is suspected.
