An arteriovenous malformation associated ischemic colitis in the setting of acute gastrointestinal clostridium difficile colitis and intestinal amebiasis: A case report

Background: There is one reported case of inferior mesenteric arteriovenous malformation presenting as ischemic colitis after an episode of gastrointestinal infection. We documented this case to emphasize the possible asso-ciation between ischemic colitis and vascular malformations. In addition, this is the number 15th case in the literature about this association. Case summary: A 40 years old male patient presented with abdominal pain and diarrhea of 10 days duration after he was diagnosed and managed as a case of Clostridium Difficile infection and amebiasis. Computed tomography angiography revealed a vascular malformation of the inferior mesenteric artery, repeated colonoscopy showed ulceration and sloughing of the mucosa, he underwent Hartmann's procedure due to colonic ischemia diagnosed by the previous measures. Later on he had a colostomy closure and end to end colorectal anastomosis. Conclusion: There is a possible association between acute gastrointestinal infection and ischemic colitis in the setting of arteriovenous malformation.
