Adrenal angiography was performed in 8 patients with Sipple's syndrome. Seven patients had pheochromocytomas and one bilateral adrenal medullary hyperplasia. In 4 cases the pheochromocytomas were bilateral. The angiographic findings are discussed and it is concluded that no typical angiographic appearance of pheochromocytoma appears to exist.
