This case report describes a 52-year-old man who presented with 2 weeks of left lower quadrant pain and bloody stool. Computed tomography revealed a 4 cm, fat-density mass acting as a lead point for intussusception of the sigmoid colon. Surgical resection was successfully performed, and histologic evaluation confirmed the diagnosis of a pedunculated colonic lipoma. Intussusception of the colon is uncommon in adults and is often associated with malignancy, but other nonmalignant causes such as a lipoma may also present similarly with obstructive symptoms, bloody stool, and/or intermittent abdominal pain. Colonic lipoma should be considered in the differential of a patient with clinical or imaging evidence of intussusception, with primary resection leading to an excellent prognosis.
本病例报告描述了一名52岁男性，其出现左下腹疼痛和便血2周。计算机断层扫描显示一个4厘米的脂肪密度肿块，作为乙状结肠套叠的引导点。成功进行了手术切除，组织学评估证实诊断为带蒂结肠脂肪瘤。成人结肠套叠并不常见，且常与恶性肿瘤相关，但其他非恶性原因如脂肪瘤也可能表现出类似的梗阻症状、便血和/或间歇性腹痛。对于有临床或影像学证据提示套叠的患者，鉴别诊断时应考虑结肠脂肪瘤，初次切除预后良好。
