“…Rarely, LHIS can be diffuse with intra‐cavitary or intramural extensions into the heart chambers . The symptoms of LHIS include the following: a variety of atrial arrhythmias including supraventricular arrhythmias, conduction disturbances (AV block), heart failure, altered hemodynamic cardiac function, recurrent pericardial effusions, congestive heart failure, and rare unexpected sudden cardiac death . Histology of LHIS shows an unencapsulated lesion of mature fat cells, and fat cells that resemble brown fat cells (fetal fat cells) interspersed throughout cardiomyocytes that are often hypertrophied with oddly shaped nuclei without mitosis present .…”

Intrinsic and Extrinsic Cardiac Pseudotumors: Echocardiographic Evaluation and Review of the Literature

et al. 2015

Echocardiography is the most common imaging modality for the assessment of cardiovascular tumors, followed by more advanced imaging modalities, such as cardiac computed tomography or cardiac magnetic resonance imaging. Non-neoplastic lesions that may simulate a true neoplasm on imaging are termed "cardiac pseudotumors." As echocardiography is the initial imaging modality where pseudotumors are identified, it is imperative to have a fundamental understanding of pseudotumors evaluation using echocardiography. There is paucity of the literature describing the different kinds of pseudotumors. This review is an attempt to describe common cardiac pseudotumors and to classify them based on their origin. The tumors arising from cardiac structures, such as epicardium, endocardium, or myocardium, were termed as "intrinsic" while the pseudotumors with no cardiac origin were termed as "extrinsic." The more common pseudotumors are described in detail with pertinent echocardiographic features and examples.

Lipomatous hypertrophy of the interatrial septum (LHIAS) is a benign condition characterized by an abnormal deposition of adipose tissue in the interatrial septum which appears as a pseudomass with a bilobed shape. We present the case of a 68-year-old obese female patient. LHIAS is an infrequent finding, but with recent improvements in imaging it is increasingly recognized. Cardiac MRI may prove useful in its diagnosis in terms of tissue characterization, as well as for the evaluation of disease extension and haemodynamic compromise.

“…Differential diagnoses should be thought of when there is sparing of the fossa ovalis. Fat-containing neoplasms can arise in the atrial septum including cardiac lipoma, cardiac rhabdomyoma, cardiac myxoma, cardiac rhabdomyosarcoma and cardiac liposarcoma [4]. Microscopically, LHIS is characterized by fat infiltration between the myocardial fibers of the atrial septum.…”

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.
