case_images: A multiparametric prostate MR revealed a PI-RADS 5 lesion of the prostate gland and a highly suspicious mass of unknown origin in the mid anterior rectal fat, at the level of the left seminal vesicle (35 x 21 mm, Figure 1).

case_images: In addition to uptake at the primary tumour site at the prostate gland, multiple foci of increased tracer up to an SUV peak of 19.2 (SUVmax 28.0) were detected, corresponding to multiple soft tissue intraabdominal masses (Figure 2).
case_images: Axial and sagittal fused SPET/CT images of Tc-99m scan(left and right pictures) confirming functioning pelvic splenic tissue and concordant with the focal PSMA uptake seen on the PSMA PET/CT images (right and left lower images).

case_images: Full matching was observed between Tc-99m and 18F-PSMA uptake in all abdominal and pelvic lesions (Figures 3, 4), hence the diagnosis of splenosis was indirectly confirmed.
