[A case of retroperitoneal splenosis diagnosed by Tc-99m heat-damaged red blood cell scintigraphy].

Splenosis is autotransplantation of splenic tissue that usually follows traumatic rupture of the spleen and/or splenectomy. We report a case of retroperitoneal splenosis. The correct diagnosis was made noninvasively with Tc-99m heat-damaged red blood cell scintigraphy. Surgical treatment, which was not necessary in this patient, could be avoided by splenic scintigraphy.
