Introduction: An accessory spleen (AS), a benign and congenital condition, is characterized by a small nodule of splenic tissue found outside of the spleen, which can mimic a pancreatic neoplasm (p-NET). 68Ga-PET/CT is used to study lesions suspected for NET, but the radioactive tracer binds also the reticuloendothelial cells, resulting in false positives in case of AS.
Aim(s): We aimed to establish the role of scintigraphy with technetium-colloid (99mTc-colloid) in the differential diagnosis of tail p-NET and AS.
Materials and methods: We retrospectively evaluated patients with suspect of tail p-NET, suggested by uptake at 68Ga-PET/C, with histological evaluation not conclusive, underwent in 2017 99mTc-colloid scintigraphy.
