I wonder if you can help me. I had a colonoscopy recently and was told my colon looked normal. In my discharge paper it said mucosal erythema in terminal ileum of unsure signifcance. I didn't have a chance to speak to the doctor, I was discharge as soon as possible. They were running late with all their appointments. Now I have a 2 month wait for a follow up appointment and also a barium x-ray. Does anyone know what mucosal erythema terminal ileum means. I know I was being tested for crohns disease.
