Two children presented with ischemic enterocolitis, a prodrome that occurs in 80% or more of patients with the hemolytic-uremic syndrome. When the prodrome precedes the development of characteristic laboratory findings or oliguria, the diagnosis of the hemolytic-uremic syndrome often is delayed. The severity of the enterocolitis itself may overshadow renal impairment. Findings of thumbprinting on plain radiographs or on barium enema examinations allow the radiologist to suggest the hemolytic-uremic syndrome as a possible cause before renal or hematologic abnormalities become manifest.
两名儿童出现缺血性小肠结肠炎，这是溶血尿毒综合征80%或更多患者会出现的前驱症状。当前驱症状先于特征性实验室检查结果或少尿出现时，溶血尿毒综合征的诊断常常会延迟。小肠结肠炎本身的严重程度可能会掩盖肾功能损害。在普通X线平片或钡剂灌肠检查中出现的拇指印征，可使放射科医生在肾脏或血液学异常表现出来之前，就提示溶血尿毒综合征可能是病因。
