Extreme LHIS variants merit inclusion in cardiac mass differentials; extends anatomic descriptions but leaves optimal management open.
Lipomatous hypertrophy of the interatrial septum is a relatively common disorder that occasionally presents as cardiac mass. Here, we present a case of extreme lipomatous hypertrophy up to 4 cm in diameter and extending into the epicardium, posterior wall of the right atrium and the atrioventricular sulcus. Diagnosis was confirmed by transesophageal echocardiography and cardiac magnetic resonance imaging.

Pruski et al. (2021) conducted a case report in Lipomatous hypertrophy of the interatrial septum (n=1). Transesophageal echocardiography and cardiac magnetic resonance imaging was evaluated on Diagnosis of lipomatous hypertrophy. Transesophageal echocardiography and cardiac magnetic resonance imaging confirmed the diagnosis of extreme lipomatous hypertrophy of the interatrial septum presenting as a 4 cm cardiac mass.
