During a 4-year period 17 patients with pancreatic apudoma and 3 patients with cystadenoma of the pancreas were admitted to this hospital. Computed tomography correctly located 3 of 4 insulinomas examined, while angiography revealed 4 of 8, which indicates that CT may replace angiography as the primary examination of these tumors, and possibly also other types of apudomas. When CT fails angiography may demonstrate a pancreatic tumor, suggesting angiography as a supplementary examination. In cystadenoma sufficient information was obtained at CT.
