A 39-year-old previously healthy woman presented possible hematuria. An ultrasound examination showed right adrenal mass and suggested pheochromocytoma. A Tc-HYNIC-TOC SPECT/CT was performed, which incidentally detected situs inversus totalis and suspicion of polysplenia without definite normal spleen in the right upper abdomen. In order to differentiate the polysplenia from other etiologies, a heat-damaged Tc RBC scintigraphy was performed. The images showed significant activity in the multiple soft tissue nodules in the posterior right abdomen, consistent with ectopic polysplenia.
