A 43-year-old obese, alcoholic woman presented to the emergency department with a 2-day history of gradual abdominal pain. An abdominal radiograph showed termination of colonic gas at the splenic flexure. Initial laboratory examinations are unremarkable. Computed tomography of the abdomen revealed left ureteral calculi with rupture and extravasation of contrast media over the upper-third ureter. To our knowledge, the colon cutoff sign is rarely been related to ureteral rupture. Recognition of the cause of colon cutoff sign on the computed tomographic scan is important because conventional radiography is often the first imaging modality requested for patients with abdominal complaints, but cannot give a confident correct diagnosis.
一名43岁的肥胖酗酒女性因逐渐加重的腹痛2天就诊于急诊科。腹部X线片显示结肠气体在脾曲处终止。初步实验室检查无异常。腹部计算机断层扫描显示左输尿管结石伴造影剂在上段输尿管破裂及外渗。据我们所知，结肠截断征很少与输尿管破裂相关。在计算机断层扫描上识别结肠截断征的病因很重要，因为传统X线摄影通常是有腹部不适患者首先要求的影像学检查方式，但无法做出可靠的正确诊断。
