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.
心脏脂肪瘤极为罕见。本文报道了 1 例独特的左房间隔脂肪瘤突入右心房的病例，导致 54 岁男性出现症状。超声心动图和计算机断层扫描显示，房间隔和右心房内有一个形状规则、巨大且固定的肿块。唯一的表现是心悸，尽管肿块几乎填满整个心房并压迫上腔静脉。患者接受了直径 87mm、重 300-400g 的大型脂肪瘤切除术。病理检查显示成熟的脂肪细胞，证实了脂肪瘤的诊断。术后患者恢复良好，症状缓解。
