title: Generalized bone marrow metastases. High liver uptake on bone marrow immunoscintigraphy associated with extramedullary hematopoiesis.
abstract: Increased hepatic uptake and absent bone marrow uptake on bone marrow immunoscintigraphy has been reported after the formation of human antimurine antibodies. A case of generalized bone marrow metastases is presented, in whom an elevated liver uptake on bone marrow immunoscintigraphy proved to be associated with extramedullary hematopoiesis. Extramedullary hematopoiesis should be included as a possible cause of a disproportionately elevated liver uptake on bone marrow immunoscintigraphy, especially on initial studies, or on repeat studies with low human antimurine antibody titers. Tc-99m labeled BW 250/183 immunoscintigraphy may aid in the localization of suspected sites of extramedullary hematopoiesis.
