Tłuszczakowaty przerost przegrody międzyprzedsionkowej — rozpoznanie, o którym nie powinno się zapominać

Abstract

Lipomatous hypertrophy of the interatrial septum (LHIS) is a benign condition histologically described as an excessive fat deposition in the interatrial region of the heart. Since the clinical features often remain asymptomatic, it is usually an incidental finding on cardiac imaging. This report presents a case of a 63-year-old woman with a firstly diagnosed atrial fibrillation and leg oedema. Those findings were then followed by echocardiography, revealing a cardiac mass within the interatrial septum. Typical characteristics of the mass, confirmed further on both computed tomography and cardiac magnetic resonance imaging, lead to the final diagnosis of LHIS and spared the patient a surgical resection. It should be noted that cardiac lesions can be diagnosed as benign using non-invasive imaging. Such cases very seldom need treatment, therefore a correct distinction of the mass with use of multimodality imaging techniques can help in making proper diagnosis and qualification to surgical interventions.
