Ultrasonic fi nding of dumbbellshaped lipomatous hypertrophy of interatrial septum

Benign lipomatous formations rank second in frequency among primary cardiac tumors. According to the degree of encapsulation, they are divided into two groups — adipose tumors and lipomatous hypertrophies of interatrial septum. Cases of lipomatosis of the heart and lipomatous hypertrophy of interatrial septum were described in scientifi c editions in years past. Interest in this pathology is related to the question: is it necessary to perform preventive surgical intervention before the appearance of clinical signs of endocardial hemodynamics disturbance? Moreover, the risk associated with surgery is much higher than the existence of a benign hyperplastic process in the anatomical structures of the heart.

Extreme lipomatous hypertrophy of the interatrial septum presenting as cardiac mass extending into the pericardium, confirmed by cardiac magnetic resonance

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.

Right Atrial Mass in a Patient With COVID-19 Pneumonia: a case report

Lipomatous hypertrophy of the interatrial septum (LHIAS) is a benign cardiac tumor. Differential diagnosis of LHIAS consists of atrial masses such as myxomas or lipomas. Herein, we report a 66-year-old male, admitted as a case of severe COVID-19 and was found to have a LHIAS extending to the crista terminalis.

Imaging Findings of Lipomatous Hypertrophy of the Interventricular Septum: A Case Report

Primary cardiac tumors are rare. We report a case of lipomatous hypertrophy of the interventricular septum in a healthy, asymptomatic, 16 year old female, diagnosed initially by echocardiogram. Non contrast Computed tomography (CT) and Cardiac magnetic resonance imaging (CMR) were also performed to confirm the diagnosis of this rarely reported condition. Lipomatous hypertrophy of the interventricular septum is a rare form of benign cardiac tumor characterized by the proliferation of adipose tissue (fat) in the interventricular septum. This clinical entity has to be differentiated from cardiac lipoma which is a benign, encapsulated tumor. CMR helps is differentiating between the 2 conditions. As the lesion was neither causing compression of the ventricle nor obstruction to blood flow, she was managed conservatively and advised follow up.

Telocytes/CD34+ Stromal Cells in Pathologically Affected White Adipose Tissue

We studied telocytes/CD34+ stromal cells (TCs/CD34+SCs) in pathologically affected white adipose tissue after briefly examining them in normal fat. To this aim, we reviewed pathological processes, including original contributions, in which TCs/CD34+SCs are conserved, increased, and lost, or acquire a specific arrangement. The pathologic processes in which TCs/CD34+SCs are studied in adipose tissue include inflammation and repair through granulation tissue, iatrogenic insulin-amyloid type amyloidosis, non-adipose tissue components (nerve fascicles and fibres in neuromas and hyperplastic neurogenic processes) and tumours (signet ring carcinoma with Krukenberg tumour and colon carcinoma) growing in adipose tissue, adipose tissue tumours (spindle cell lipoma, dendritic fibromyxolipoma, pleomorphic lipoma, infiltrating angiolipoma of skeletal muscle and elastofibrolipoma), lipomatous hypertrophy of the interatrial septum, nevus lipomatosus cutaneous superficialis of Hoffman–Zurhelle and irradiated adipose tissue of the perirectal and thymic regions. Two highly interesting issues emerged: (1) whether the loss of CD34 expression in TCs/CD34+SCs is by changes in marker expression or the disappearance of these cells (the findings suggest the first possibility) and (2) whether in some invasive and metastatic malignant tumours, TCs/CD34+SCs that completely surround neoplastic cells act as nurse and/or isolating cells. Further studies are required on adipose tissue TCs/CD34+SCs, mainly in lipomatosis and obesity.

A patient with chronic dyspnea and episodes of paroxysmal atrial fibrillation in the presence of a right atrial mass

Lipomatous Hypertrophy of the Interatrial Septum (LHIS) is an unusual condition that can be presented as a mass-like bulge that typical spares of the fossa ovalis. We describe a 73-year-old overweight woman with dyspnea on exertion and two episodes of paroxysmal atrial fibrillation for the last eight months. A big sessile mass was detected in the interatrial septum measuring 3.7 x 4.7cm during transesophageal echocardiography. The patient underwent resection of the mass and pericardial patch reconstruction of the defect with significant improvement of her clinical status during the follow-up period. The histopathological analysis suggested LHIS.
