We report a case of Q fever demonstrated on 99mTc methylene diphosphonate bone scan and fluorodeoxyglucose (FDG) PET/CT.
A 66-year-old man with newly diagnosed, low-grade prostate cancer presented with abdominal and bone pain. Bone scan revealed multiple lesions suspicious for prostate cancer metastases. Because of liver abnormalities on noncontrast CT, an FDG PET/CT was performed and demonstrated FDG-avid sclerotic bone lesions, infiltrative liver disease, and retroperitoneal adenopathy. This appearance, thought unusual for low-grade prostate cancer, prompted extensive clinical evaluation for several months. Liver and iliac bone biopsies showed noncaseating granulomas without neoplasia. Extensive serologic evaluation eventually demonstrated elevated Q fever titers.
