title: [Angiographic aspects of tumors of the islet of the pancreas].
abstract: Four patients with islet cell tumours were explored with selective angiography. The radiological findings of 3 insulinomas and 1 nonfunctioning tumor are described. The typical hypervascular pattern of parenchimatose phase was found in all. The three insulinomas were successfully treated surgically. The nonfunctioning tumor was not removed due to the pathologists original impression that it was a maligant tumor involving the portal vein. Angiographic pattern, etiology, differential diagnosis and causes of errors are discussed. The method is diagnostically useful and offers important precperative information thus reducing operating time and minimizing the magnitude of the surgery.
