title: Radiation-induced solitary rectal ulcer.
abstract: A case of radiation-induced solitary rectal ulcer is presented. The unusual posterior location with involvement of the internal iliac artery produced massive lower intestinal hemorrhage. Temporary control was obtained with percutaneous arterial catheter embolization, but definitive control necessitated surgical resection.
