Overview

On CT scan VIPoma is characterized by hypervascularity with diffuse multiple metastatic nodulation.

CT

• On CT scan VIPoma is characterized by hypervascularity with diffuse multiple metastatic nodulation.
• CT scan are highly accurate for tumor localization of primary neuroendocrine pancreatic tumor. Since most of them are more than 2cm in size at the time of presentation.
• Sensitivity of contrast enhanced CT for VIPoma approaches 100%.

Note presence of varices as well as invasion of tumor into the fourth portion of the duodenum.
