In order to evaluate the radiological findings of gastrointestinal carcioid tumors, the subjects of our study were 11 cases of histologically-confirmed gastrointestinal carcinoid tumors. we evaluated the location, tumor size, and radiological changes of the adjacent soft tissues, along with metastatic lesions barium studies of the gastrointestinal tract and abdominal computed tomography(CT). In 4 out of 5 cases of gastric carcinoid tumor, UGI examination revealed gastric carcinoma-like features such as a large mass with central ulceration. Gastric carcinoid tumor, a small bowel series revealed a mesenteric mass with the narrowing, fixation, and ulceration of the adjacent jejunal loop. In 3 cases of colonic and rectal carcinoid tumor, barium enema revealed an annular constricting or a polypoid mass. Contrast-enhanced CT scan showed various sized homogeneous masses on each primary site. Perirectal fat infiltration was noted in the rectal carcinoid tumor, along with the obliteration of peripancreatic fat and enlargement of the celiac and left gastric lymph nodes in the duodenal carcinoid tumor. multiple heterogeneous low-density masses, the metastatic lesions from the gastric, small bowel, colonic carcinoid tumor in each one, were noted in the liver. The size of the primary lesion causing the metastasis was more than 2cm. It is difficult to diagnose gastrointestinal carcinoid tumors because the clinical features are nonspecific and radiologic findings mimic gastrointestinal carcinoma. Still, we should interpret radiologic studies with the possibility of carcinoid tumor in mind if the following points are present: carcinoid syndrome, small-sized gastric submucosal mass with massive bleeding, or mesenteric mass with surrounding mesenteric radial pattern thickening on abdominal computed tomography.
