Chest radiography showed small opacity in the left lower lobe (Figures 1(a) and 1(b), arrow).
Cardiac magnetic resonance imaging showed a hypointense tumorous mass ((a), (b), and (c) arrows) extending from the internal wall of pericardium towards the adjacent wall of the left ventricle with a clear adipose line between the mass and the left ventricle. Pathology (d) showed cavernous hemangioma with some myocardial tissue denaturation, partial cardiac collagen degeneration, hypertrophy, and enlargement of the nucleus and immunostaining showed positive Ki-67 and negative SMA. Hematoxylin and eosin staining. Magnification, x100.

Cardiac magnetic resonance was obtained with four-chamber (Figure 2(a)) and coronal (Figure 2(b)) view depicting a hypointense tumorous mass (48 mm x 57 mm) extending from the internal wall of pericardium towards the adjacent wall of the left ventricle with the left ventricle being squashed severely (arrow). Cardiac cine magnetic resonance imaging demonstrated a clear boundary of the mass and the ventricular ejection fraction was 49% (Figure 2(c)). Consequently, a total resection of the mass together with part of the left atrial appendage was performed and pathology showed cavernous hemangioma with some myocardial tissue denaturation, partial cardiac collagen degeneration, hypertrophy, and enlargement of the nucleus (Figure 2(d)); immunostaining showed positive Ki-67 and negative SMA.
