Reversibility of anatomical and functional asplenia by chronic transfusion in a child with sickle cell anemia.

We describe a 13-year-old black girl with sickle cell disease in whom spleen regrew after autosplenectomy during the course of a transfusion program for a cerebrovascular accident. This case illustrates the remarkable regrowth potential of the shrunken and fibrotic spleen when sickled red cells are replaced with normal cells.
