Post-traumatic intrahepatic splenosis mimicking a neuroendocrine tumour

A 52-year-old man presented with abdominal pain with a background of splenectomy 25 years previously. Initial investigations lead to suspicion of a neuroendocrine tumour. Positron emission tomography octreotide scanning and chromogranin were raised. He subsequently underwent a lateral segmentectomy. The histopathology was consistent with splenosis. 1. Splenosis must be considered as differential in any patient with abdominal symptoms post-traumatic splenectomy. 2. Positron emission tomography (PET) octreotide scanning can detect splenosis giving false positives for a neuroendocrine tumour. This is the first case to describe such an association.
