Intrapancreatic accessory spleen detected by 68Ga DOTANOC PET/CT and 99mTc-colloid SPECT/CT scintigraphy

Clin Nucl Med. 2015 May;40(5):415-8. doi: 10.1097/RLU.0000000000000601.

Abstract

A 77-year-old man was referred to our center for a suspected neuroendocrine neoplasm in the pancreatic tail, incidentally detected at CT. Ga DOTANOC PET/CT showed intense tracer uptake in the pancreatic lesion. At MRI, the lesion was similar to the spleen on all sequences, suggesting the presence of intrapancreatic accessory spleen. A Tc-colloid SPECT/CT scan performed to differentiate spleen tissue from neuroendocrine tumor revealed a focal uptake in the pancreatic lesion, thus confirming the presence of ectopic spleen and avoiding unnecessary surgery.
