Positive 111In-granulocyte scintigraphy in a patient with focal leukemic blast cell infiltrations.
A patient with acute myeloid leukemia was investigated with 111In-granulocyte scintigraphy to reveal possible sites of infection. 111In-granulocytes accumulated in areas of leukemic blast cell infiltration leading to a false-positive scintigram. This possibility must be kept in mind when studying leukemic patients using labeled leukocytes.
