We report the case of a male in his early 30s who presented with a large prolapsed anal mass, a single episode of rectal bleeding and a 1 day history of lower abdominal pain. Contrast-enhanced CT imaging of the abdomen and pelvis revealed a 4.4 cm lipomatous mass protruding through the anal canal, originating from the sigmoid colon, which had intussuscepted into the rectum and anus. The patient was successfully managed with flexible sigmoidoscopy and excision of the mass. Histopathological examination confirmed the diagnosis of a colonic lipoma.
我们报告了一名30岁出头男性的病例，该患者出现巨大的肛门脱垂肿物、单次直肠出血以及1天的下腹部疼痛病史。腹部和盆腔的增强CT成像显示，一个4.4厘米的脂肪瘤样肿物经肛管突出，起源于乙状结肠，已套叠入直肠和肛门。该患者通过乙状结肠镜检查和肿物切除得到了成功治疗。组织病理学检查确诊为结肠脂肪瘤。
