title: Preoperative computed tomography and scintigraphy to facilitate the detection of accessory spleen in patients with hematologic disorders.
abstract: Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.
