Imaging Studies

Bone involvement is common. Approximately 50% of patients have lytic bone lesions demonstrated on radiographs, and 70% of patients show increased uptake using technetium scintillography ("hot spots"). Destructive lesions resembling osteomyelitis are demonstrated on radiographs in 25% of patients. Multifocal osteolytic cysts may be evident as tender bones and can be detected as hot spots by technetium scintillography.
