Intramural colonic haematoma with fistula formation in a haemophiliac.

This paper describes a haemophiliac patient with an intramural haematoma of the ascending colon resulting in fistula formation between the colon and the iliacus muscle. This part of the bowel had been by-passed at surgery and stasis ulceration of the musoca overlying the haematoma may have contributed to the formation of the fistula.
