Duodenal Carcinoid Tumors

7 Contrast enhanced CT demonstrates multiple low-density lesions in the duodenum near the ampulla. These appear hyperdense on the arterial phase images. This appearance can be seen in neuroendocrine neoplasms such as carcinoid tumors or gastrinomas. Occasionally, gastrointestinal stromal tumor is tumors can have a similar appearance on CT. Metastasis from primary such as renal cell carcinoma could also have a similar CT appearance. Biopsy was performed and revealed duodenal carcinoid tumors.
