Key Words: Cardiomegaly Supraventricular tachycardia Epicardial lipoma
A 25-year-old female presenting with a supraventricular tachycardia. Chest radiograph revealed cardiomegaly (Fig. 1
). Contrast enhanced CT demonstrated a large epicardial mass, originating from the left atrioventricular groove, (Hounsfield units equal to fat) containing blind ending vessels (Fig. 2
a). Completely excised, the mass weighed 2.5 kg. Histology confirmed an epicardial lipoma (Fig. 2b and c).

Fig. 2. (a and b) Contrast enhanced axial CT chest reveals a large epicardial mass with blind ending vessels and Hounsfield units equal to fat. There is a normal transverse cardiac index, with the arrows indicating the large diameter of the lipoma. (Insert) Micrograph with hematoxylin and eosin stain (H&E) x200 demonstrates blood vessels embedded in mature fat. There are no special features to this lipoma. (c) Intraoperative photo with the large epicardial mass as seen through a combined sternotomy/left anterior thoracotomy approach.
