Labeled leukocyte scans for detection of retained polyurethane foam

Complete removal of an infected polyurethane-covered breast prosthesis is difficult, and retained tissue-embedded foam can form a nidus for persistent infection. Scanning the chest wall after administration of indium-111 oxine-labeled autogenous leukocytes will locate areas of infection around retained fragments of foam, thereby facilitating their removal and allowing eventual successful reconstruction. This technique may deserve wider application for locating infected foreign bodies in a variety of patient problems.
