Angiography in primary myomas of the alimentary tract

Fifteen cases of smooth muscle tumor of the alimentary tract were collected for analysis from several institutions. The findings showed that angiography is the best method available for diagnosis and evaluation of such tumors but is unable to differentiate benign from malignant lesions unless arterial invasion is detected. Computer tomography, ultrasound, and angiography are compared in the diagnosis of one case. Additionally, the angiographic pattern of a leiomyoblastoma is presented, presumably for the first time.
