Angiography in expansile lesions of the spleen.
The angiographic findings in a relatively large number of expansile lesions of the spleen are presented. In cysts our findings correspond to those in earlier reports, the hallmark being stretching of intrasplenic arteries and veins around an avascular espansile lesion. As to neoplasms (primary as well as secondary), however, our findings suggest that the criteria of malignancy, that is, neovascularity, vascular encasement, and arteriovenous shunting, may be more frequent than is evident from earlier reports.
