title: Positive 99mTc-pertechnetate scan in a child with intestinal arteriovenous malformation.
abstract: A teenager with massive rectal bleeding had a positive 99mTc-pertechnetate abdominal scan. At laparotomy, an arteriovenous malformation of the jejunum was found. There was no evidence of a Meckel's diverticulum. The persistent problem of the positive technetium scan warrants increased utilization of preoperative visceral angiography.
