“…Lipomatous hypertrophy of the atrial septum is characterized by a septal thickness of over 2 cm, with a symmetric dumb-bell shape and sparing of the fossa ovalis. 6,7 The mass in this patient spared the fossa ovalis but RIGHT ATRIAL MASS AND A PSEUDOMASS only involved the superior limb of the atrial septum.…”

“…A distinction between lipoma and lipomatous hypertrophy is often made although pathologically they are similar. Lipomatous hypertrophy of the atrial septum is characterized by a septal thickness of over 2 cm, with a symmetric dumb‐bell shape and sparing of the fossa ovalis 6,7 .

A Right Atrial Mass and a Pseudomass

Right atrial (RA) masses are rare entities often detected incidentally during imaging studies. Leading etiologies of right atrial masses are tumor, thrombi, and vegetations. We present two cases of right atrial masses, a cardiac lipoma and an artifact. Clinical and echocardiographic characteristics of benign cardiac tumors are reviewed. We then highlight the importance of considering artifact in the differential diagnosis of atrial masses. Finally, we discuss echocardiographic characteristics of right atrial masses that may provide clues for diagnosis. Right atrial masses, often detected incidentally during imaging studies, are uncommon and can be due to many etiologies including tumors, thrombus, vegetations, normal variants, and artifacts. We describe 2 patients with RA masses detected on routine transthoracic echocardiogram.

“…As far as we know, to date, only two authors have reported LAH with RA free wall involvement [ 4 , 5 ]. Different from these authors, who described cases of deposition of adipose tissue both in the interatrial septum and in the RA free wall, in our case, the LAH was limited to a portion of the RA free wall only.…”

Lipomatous atrial hypertrophy (LAH) is a benign cardiac lesion characterized by fat accumulation in the interatrial septum that spares the fossa ovalis. It is associated with obesity and is more frequently observed in elderly and female patients. It is most often detected as an incidental finding on transthoracic echocardiography (TTE). The deposition of adipose tissue may rarely involve both the interatrial septum and the right atrial (RA) free wall. Herein, we describe an extremely rare case of LAH limited to a portion of the RA free wall only, mimicking a myxoma or a thrombotic formation. A multi-instrumental evaluation comprehensive of TTE implemented with pulsed-wave tissue Doppler imaging (PW-TDI), transesophageal echocardiography (TEE), and computed tomography (CT) angiography, performed during the patient's stay in the emergency department, allowed to quickly diagnose the benign RA pseudomass.

“…Besides being usually benign and asymptomatic, a significant number of patients have been reported to have unexplained arrhythmias such as atrial fibrillation, atrioventricular (AV) block and sudden death [10]. Therefore, in most patients, it represents an incidental echocardiographic finding requested for further examination after arrhythmias presentation [11]. Noninvasive modalities have led to the identification of these masses, which may be mistaken for a tumor or other neoplasm.…”

Lipomatous Hypertrophy of the Interatrial Septum is (LHAS) an unusual and benign condition characterized by the excessive deposition of adipose tissue in the interatrial septum, which is most often detected as an incidental finding on echocardiography. The classic finding is a homogenous, bi-lobed configuration of the interatrial septum with sparing of the fossa ovalis. LHAS has been associated with various atrial arrhythmias, including multifocal atrial tachycardia, multiple premature atrial contractions, atrial fibrillation and rarely sudden death. Here the author describes a case report of a 57-year-old obese female who presents to the emergency department for sudden palpitation and dizziness due paroxysmal atrial fibrillation with rapid ventricular response. After successful cardioversion, a tranthoracic bidimensional echocardiography showed the typical finding of LHAS.
