Silent Left Ventricular Hemangioma.
Cardiac hemangiomas are extremely rare, and account for 5-10% of benign cardiac tumors. Most clinical presentations involve patient dyspnea on exertion and arrhythmia; asymptomatic patients are uncommon. A 45-year-old man had an asymptomatic left ventricular mass that was found incidentally during an echocardiogram. Magnetic resonance images showed an isointense protruding mass attached to the lateral wall of the left ventricle. The patient underwent a complete surgical resection with a good outcome. Histopathological examination revealed a cavernous hemangioma. The natural course of cardiac hemangiomas varies, and total resection is the favored treatment.
