We had a case of nonfunctional pancreatic endocrine tumor with splenic metastasis. The patient was 63-year-old woman as a HBV carrier followed for long time. For abdominal CT showed a tumor at tail of pancreas and spleen, she was admitted to our hospital. Abdominal MRI revealed a tumor thrombus in splenic vein and a large tumor expanded from body and tail of pancreas to spleen. We suspected that a tumor occurred from spleen because that tumor was existed in spleen larger than in pancreas and performed distal pancreatectomy with splenectomy. Pathological diagnosis was malignant endocrine tumor in pancreas and splenic metastasis. Malignant endocrine tumor which is rare relatively have good prognosis, compared with pancreatic adenocarcinoma. However, this case has splenic invasion. We need to follow up her carefully.
