Handheld gamma probe localization of accessory splenic tissue in recurrent idiopathic thrombocytopenic purpura

Recurrent idiopathic thrombocytopenic purpura due to residual splenic tissue after splenectomy is uncommon. Location of the offending splenic tissue can be technically demanding. A small accessory spleen was localized intraoperatively with a handheld gamma probe after standard technetium-labeled heat-damaged red blood cell scan of the liver and spleen.
