Colon cancer is the third leading cause of cancer worldwide. On presentation, 20% of patients will have metastatic disease, and the most common sites for metastatic colon cancer are liver, lung, and peritoneum. Our patient was a 55-year-old man with a history of rectal adenocarcinoma cancer and colectomy surgery for the past 2 years, who had presented changes in bowel movements, rectal bleeding and thin. In the new visit and positron emission tomography-computed tomography scan, the results showed that there are two ill-defined foci of increased FDG (F-fluorodeoxyglucose) uptake in the body (metabolic diameter = 26 mm, SUVmax = 7.8) and tail (metabolic diameter = 13 mm, SUVmax = 7.4) of the pancreas gland, persisting on delayed images. Colon cancer metastasis to the pancreas is rare. The presence of masses in both the colon and pancreas could be a result of metastasis from the pancreas to the colon, metastasis from the colon to the pancreas, or synchronous primary cancers.
Keywords: colon cancer; metastasis; pancreas.
