Interesting image. Aseptic loosening of elbow prostheses diagnosed on F-18 FDG PET/CT.

摘要

A 35-year-old woman, having recurrent pain after total elbow arthroplasty, was subjected to positron emission tomography/computed tomography with fluorodeoxyglucose (FDG PET/CT) to rule out infected orthopedic hardware. A diagnosis of aseptic loosening was made based on the gram staining and 9 months of clinical follow-up. This case report highlights the utility of FDG PET/CT in evaluation of painful elbow prostheses and describes the FDG uptake pattern in confirmed case of aseptic loosening.
