This article reports the selective angiographic findings and surgical and pathological findings in 4 patients with islet cell tumors. The 4 patients were diagnosed as islet cell tumors by clinical and laboratory examinations, but CT and ultrasound examinations were not abnormal. Selective celiac arteriography showed that there were tumors in the pancreas in 3 patients and no abnormalities in one case. Surgical and pathological specimens confirmed: In 3 cases of positive tumors, the angiography was consistent with the findings of the operation; in 1 case, the tumor was small and located in the tail of the pancreas. The article discusses the diagnostic value of angiography and considers that such patients undergo angiography before surgery.
