The angiographic features of leiomyomatous tumors of the small bowel are described in three cases. Selective celiac and superior-mesenteric angiography disclose large, sometimes multiple, feeding arteries and draining veins. There are many irregular tumor vessels and dense staining, venous pooling and early venous filling. The margins are well circumscribed and correspond to the true size of the mass. The differential diagnostic problems between benign and malignant leiomyomatous lesions and the angiographic features of metastatic leiomyosarcoma in the omentum and the liver are also described.
