Infections due to Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) are often mild and self-limiting, but more severe cases can develop into hemolytic uremic syndrome (HUS) and hemorrhagic colitis. This case report documents a sporadic case of ischemic colitis likely triggered by EHEC but without manifestations of hemolytic uremic syndrome. From our literature review, we identified only one other case of an EHEC infection presenting as ischemic colitis in the absence of HUS. To our knowledge, this is the first case presentation of EHEC-induced ischemic colitis which did not lead to significant morbidity.
