Overview

Abdominal CT scan may be helpful in the diagnosis of Zollinger-Ellison syndrome caused by gastrinoma. Gastrinomas are frequently multiple and often extrapancreatic (90% located in the gastrinoma triangle). Thus, they can be difficult to locate. For this reason, multiphase contrast enhanced thin slice cross-sectional imaging is ideal. Findings on Abdominal CT scan suggestive of gastrinoma include clearly defined, well-enhanced mass.

• Abdominal CT scan can be used to confirm the location of the cancer and to detect distant metastasis.
