Abstract

A 26-year-old renal transplant recipient presented to our unit with passage of fresh and altered blood. He was on multiple immunosuppressants including mycophenolate mofetil, tacrolimus, and prednisolone. He was profoundly anaemic on admission, requiring up to 10 units of packed cell transfusion. Oesophagogastroduodenoscopy and colonoscopy showed no bleeding source. Subsequent enteroscopy showed several ulcers in the ileum, while biopsy showed cytomegalovirus viral inclusions. He was treated with a 3-week course of valganciclovir. Re-scope 1 month after the enteroscopy showed that the ulcers were largely healed.
