Tamponade caused by cardiac lipomatous hypertrophy.
Myerson SG., Roberts R., Moat N., Pennell DJ.
Cardiac lipomatous hypertrophy is an unusual disorder that typically affects the interatrial septum. We report a case in which large subpericardial deposits of fat were initially mistaken for a pericardial effusion and the subsequent clinical picture resembled tamponade. The patient improved following a pericardiectomy.
