A case of occult insulinoma localized by pancreatic dynamic enhanced spiral CT

Figure 2 Images of pancreatic dynamic enhanced spiral CT showed the localization of the insulinoma (white arrows). It was in the body of the pancreas (adjoining the neck). The tumor started to enhance from 45 s after the onset of contrast material injection, and could be seen until 85 s. As the contrast between the insulinoma and the pancreas was not obvious, the tumor was difficult to find by other conventional imaging techniques.
