Giant Interatrial Septal Lipoma Filling the Right Atrium Causing Slight Symptoms: A Case Report
Giant Cardiac Lipoma
Keywords:cardiac tumor, cardiac lipoma, computed tomography angiography
Cardiac lipoma is extremely rare. Here, we present a unique illustrative case of an interatrial septal lipoma protruding into the right atrium, causing symptoms in a 54-year-old male. Echocardiogram and computed tomography showed a well-shaped, giant, and fixed mass located in the interatrial septum and right atrium. The only manifestation was palpitation, though the mass filled almost all of the atrium and compressed the superior vena cava. The patient received resection of the large-sized lipoma, which was 87mm in diameter and weighed 300-400g. Pathological exam demonstrated mature lipocytes and substantiated the diagnosis of lipoma. The patient did well postoperatively, and symptoms were resolved.
