Evaluation of a patient with splenosis by various imaging modalities.

Three different noninvasive imaging procedures were performed in a patient after an intravenous pyelogram suggested a suprarenal mass. Presence of a mass was confirmed by ultrasonogram. Computed tomography revealed two masses in the splenic bed that showed contrast enhancement. Radionuclide scans demonstrated multiple splenic masses (splenosis). The specificity of the splenic tissue as well as the anatomic resolution were best with the radionuclide liver and spleen scan.
