A 67-year-old female presented with a 1-year history of exertional dyspnoea. Echocardiography showed a mass in the right atrium. Surgery revealed a lipoma on the interatrial septum, near the superior cavoatrial junction. This was excised leaving the atrial septum intact. Histopathology confirmed a benign lipoma. The patient improved symptomatically after surgery and no recurrence was seen after 1 year. These rare masses are the accumulation of mature adipose tissue, arising from the subepicardial layer. Due to benign pathology and slow growth, right atrial lipomas may be resected without interatrial septum resection, avoiding the potential complications of more radical surgery.
一名67岁女性因劳力性呼吸困难就诊，病史1年。超声心动图显示右心房有一肿块。手术发现房间隔靠近上腔静脉心房连接处有一脂肪瘤。将其切除，房间隔保持完整。组织病理学证实为良性脂肪瘤。患者术后症状改善，1年后未见复发。这些罕见的肿块是成熟脂肪组织的积聚，起源于心外膜下层。由于病理性质为良性且生长缓慢，右心房脂肪瘤可在不切除房间隔的情况下进行切除，避免了更激进手术的潜在并发症。
