Enterobius vermicularis infection is typically observed in paediatric patients and manifests with perianal pruritus, but other manifestations or ectopic presentations have been reported in the literature. We present the case of a man in his 60ss with a large-bowel obstruction with symptoms including a 4-day history of progressive abdominal pain, distension, vomiting and absolute constipation. On examination, his abdomen was distended with tinkling bowel sounds on auscultation. Cross-sectional imaging demonstrated an obstructing mass in the distal descending colon. An emergency laparoscopic Hartmann's procedure was performed and the patient made an uneventful recovery. An intraoperative colonoscopy demonstrated numerous white threadworms in the colon. Histological analysis demonstrated a pseudotumour related to Enterobius vermicularis infection. This case represents a rare differential diagnosis for a large-bowel obstruction.
蛲虫感染通常见于儿科患者，表现为肛周瘙痒，但文献中也有其他表现或异位表现的报道。我们报告了一例 60 多岁男性的大肠梗阻病例，其症状包括 4 天的进行性腹痛、腹胀、呕吐和完全性便秘。体格检查发现患者腹部膨隆，听诊肠鸣音亢进。横断面成像显示降结肠远端有梗阻性肿块。行紧急腹腔镜下 Hartmann 手术，患者恢复顺利。术中结肠镜检查显示结肠内有许多白色线虫。组织学分析显示与蛲虫感染相关的假肿瘤。本例代表了大肠梗阻的一种罕见鉴别诊断。
