title: Discordant response to chemotherapy between lymphadenopathy and bone lesions on gallium-67 scanning in Hodgkin's disease.
abstract: A 33-year-old woman with a diagnosis of Hodgkin's disease had a prechemotherapy whole-body Ga-67 scan to document gallium avidity of lesions and to assess response to therapy. A posttherapy scan showed a discordant response with complete resolution of lymphadenopathy and persistence of bone lesions. Radiographic evaluation of the left humerus, radius, and ulna demonstrated typical fibrous dysplasia as a cause for persistence of Ga-67 activity and shoulder activity probably representing arthropathy. She was in remission 3 years later although she fell and fractured the humerus through the bony lesion, and biopsy at the time of internal fixation confirmed fibrous dysplasia.
