Computerized tomography appearances of pelvic haemangioma involving the large bowel in childhood.

The Computed Tomography (CT) appearance of a pelvic haemangioma involving the rectum in two children, one with the Vater association and one with Klippel-Trenaunay syndrome, is described. Both cases complained of painless rectal bleeding and the diagnosis was suggested by the presence of pelvic phleboliths on the plain abdominal radiograph. CT provides a simple, non-invasive method of diagnosing such lesions and assessing their extent.
