In a patient who presented with pelvic pain and changed bowel habits, barium enema and sigmoidoscopic examinations demonstrated a nonspecific asymmetric narrowing of the colon at the rectosigmoid junction with normal mucosal appearance. Computed tomography revealed the etiology to be retroperitoneal fibrosis with pelvic extension and entrapment of the colon at this level. The importance of CT in diagnosis of this unusual manifestation of retroperitoneal fibrosis is discussed.
一名出现盆腔疼痛和排便习惯改变的患者，钡剂灌肠和乙状结肠镜检查显示，在直肠乙状结肠交界处结肠有非特异性不对称狭窄，黏膜外观正常。计算机断层扫描显示病因是腹膜后纤维化并向盆腔蔓延，导致该水平的结肠受压。本文讨论了CT在诊断这种腹膜后纤维化异常表现中的重要性。
