Evaluate patients who have a relapse after having an initially satisfactory response to splenectomy for the possible presence of an accessory spleen. [82, 83]

  • An accessory spleen is strongly suggested if Howell-Jolly bodies appeared on the peripheral smear after splenectomy but are no longer present. However, the continued presence of Howell-Jolly bodies does not exclude an accessory spleen.

  • Imaging techniques using radionucleotide-labeled sulfur colloid, heat-damaged RBCs, or, preferably, autologous platelets provide more useful information than standard imaging with CT scanning or MRI.
