摘　　要：BACKGROUND Ischemic colitis with inferior mesenteric arteriovenous malformation(AVM)is a rare disease.Although a few reports have been published,no report has described the natural history of idiopathic mesenteric AVM.CASE SUMMARY A 50-year-old male was admitted to our hospital due to abdominal pain that had persisted for 3 mo and bloody diarrhea.He had no history of trauma or abdominal surgery.He had undergone two colonoscopies 6 mo and 2 years ago,and they showed only a polyp.He was diagnosed with ischemic colitis with inferior mesenteric AVM following contrast-enhanced abdominal computed tomography(CT)and underwent rectal low anterior resection.He has not had a recurrence of symptoms for 3 years.His history showed that he had undergone non-enhanced abdominal CT 2,5,and 8 years ago when he had attacks of urinary stones.Retrospectively,dilation of blood vessels around the rectosigmoid colon could have been detected 5 years ago,and these findings gradually became more evident.CONCLUSION This is the first report of the natural history of inferior mesenteric AVM.
