title: Intestinal leiomyomas: angiographic imaging.
abstract: A retrospective angiographic study was done on 19 patients with solitary leiomyomas of the small bowel, one patient with multiple leiomyomas, and two patients with leiomyosarcomas. All patients had gastrointestinal bleeding but no small bowel obstruction. Selective mesenteric angiography was the main diagnostic procedure. Tumoral hypervascularity and dense capillary staining within a well-circumscribed mass were present in all patients. Prominent and irregular feeding arteries were seen in 19 cases and prominent draining veins in 20. Contrast extravasation indicating the site of active bleeding was shown in two patients.
