A 27-year-old man with no medical history presented with ventricular tachycardia at 160 beats/min with right bundle branch block and left axis. Transthoracic echocardiography showed an echogenic mass inferolateral through anterolateral (96 × 72 × 65 mm). Evaluation using magnetic resonance imaging demonstrated an intramyocardial process extending up to the left atrium. Intermediate signal intensity on T1-weighted images (A,Online Video 1) and high signal intensity on T2-weighted images (B) combined with heterogenous hyperintense contrast enhancement were consistent with a hemangioma. Blood supply and coronary anatomy were analyzed using coronary angiography, which revealed a rich vascular structure originating from the posterolateral branches of both the right coronary artery and the ramus circumflex (C,Online Videos 2 and 3). Biopsy confirmed intramural hemangioma without histologic signs of malignancy (D). The patient is treated with beta-blockers and remains in good clinical condition. Six-month follow-up magnetic resonance imaging showed a decrease in volume from 264 to 177 ml.
