A recurrence of pancreatic non-functioning neuroendocrine tumor mimicking splenosis.

There have been a number of case reports where intra-abdominal splenosis or accessory spleens have mimicked metastatic cancer. However, to the best of our knowledge, this to be the first report of a Tc-99m phytate scintigraphy study in English literature showed the uptake in the metastatic mass of pancreatic NET which had been resected for 19 years ago. Although a nuclear scintigraphy is useful method to differentiate between abdominal splenosis and metastatic cancer, the histopathological confirmation should be considered.
