We present the clinical case of a 72-year-old male with a history of diabetes mellitus, systemic arterial hypertension and chronic kidney disease who, days after starting hemodialysis therapy, presented a clinical picture of hematochezia. A diagnostic colonoscopy was performed, finding ischemic pancolitis. The histopathological report corroborated this and the subsequent immunohistochemistry showed the presence of cytomegalovirus (CMV). Ischemic colitis in the context of CMV infection is one of the less common forms, so the diagnosis requires high clinical suspicion and the use of targeted paraclinical studies.
