Crohn's disease and lymphoma limited to the small bowel may have similar clinical and radiologic features. This diagnostic dilemma was encountered in 5 adolescent patients with an eventual diagnosis of Crohn's disease, all of whom had normal sigmoidoscopic and radiographic evaluations of the colon. Rectal and colonic biopsies in 3 revealed granulomas and focal colitis supportive of the diagnosis of Crohn's disease and prevented laparotomy. A careful search for occult colonic involvement in similar patients with Crohn's disease may obviate the need for diagnostic surgery.
局限于小肠的克罗恩病和淋巴瘤可能具有相似的临床和放射学特征。5例最终诊断为克罗恩病的青少年患者遇到了这种诊断难题，他们所有人的乙状结肠镜检查和结肠影像学评估均正常。3例患者的直肠和结肠活检显示肉芽肿和局灶性结肠炎，支持克罗恩病的诊断，从而避免了剖腹手术。对患有克罗恩病的类似患者仔细检查是否存在隐匿性结肠受累情况，可能无需进行诊断性手术。
