Angiographic diagnosis of endocrine tumors of the pancreas

The angiographic findings in 18 patients with endocrine tumors of the pancreas are analyzed. A literature review (262 cases) is performed in order to assess the accuracy of angiography in diagnosing islet cell tumors, in particular multiple and small (less than 1 cm) lesions. Problems of differential diagnosis of pancreatic and extrapancreatic structures and lesions are discussed.
