“…[1][2][3][4][5] Visualization of splenic tissue by leukocyte scintigraphy is based on uptake of Tc-99m HMPAO-labeled leukocytes by phagocytic Kupffer cells of the reticuloendothelial system, like colloidal substances or Tc-99m-labeled heat-damaged red blood cells. 6,7 This case highlights the possible role of Tc99m HMPAO-labeled leukocyte scintigraphy in the visualization of splenosis and the importance of whole-body imaging.…”

Splenosis is heterotopic autotransplantation and seeding of splenic tissue, and it can be found anywhere in the abdominal cavity. We present a case of multiple abdominopelvic splenosis in a postsplenectomy patient detected incidentally during Tc-99m HMPAO-labeled leukocyte scintigraphy 30 years after the traumatic event.
