    Pancreatic metastases is a rare malignant tumor, when comes to multiple cancers, it may be a challenge to identify the primary lesion of new pancreatic metastases. With the continuous advancement of imaging technology, the PET/CT has been widely used due to its high diagnostic accuracy and non-invasiveness. However, in the present case, the patient had history of limited-small cell lung carcinoma and prostatic cancer, the combined application of three kinds of PET/CT was used to identify the new metastases of pancreatic and bone metastases, which suggested high probability of primary G2 pancreatic neuroendocrine tumor with bone metastases. After the needle biopsy, samples were confirmed by diagnostic pathology as small cell lung cancer metastasizing to the pancreas and bone. The results of our case suggests the irreplaceability of pathology and possibility of misdiagnosis by PET/CT, besides, it also supplements clinical data for second primary cancers after small cell lung cancer.
