Giant Cardiac Myxoma as a Cause of Stroke.

Cardiac myxomas are the most common primary intracardiac tumors and are histologically benign. However, they are potentially dangerous because of the risk of systemic embolism. Echocardiography is the key diagnostic tool for atrial myxomas, allowing for the identification of the tumor, as well as determining its location, shape, size, and connections with adjacent cardiac structures. Surgical resection is curative in most patients, with tumor relapse and recurrent embolism being relatively rare.
