This 56 y/o male was referred for CT of the abdomen and pelvis for evaluation of hematuria. Selected post contrast axial and coronal reconstructed images shown above demonstrate enhancing intra-abdominal masses. The spleen has been removed, splenosis was considered in the differential diagnosis. Further history indicated the splenectomy was post traumatic and a sulfur colloid scan was performed. Selected images are shown above. Functioning splenic tissue correlating with the intra-abdominal masses was demonstrated confirming the diagnosis of intra-abdominal splenosis as the etiology of the masses. The patient's hematuria resolved and an etiology was never established with certainty.
