Figure 4. Radiologic findings of multiple osteolytic lesions on positron emission tomography computed tomography (PETCT) imaging. PET-CT scan after surgery shows interval right total hip replacement surgery with increased FDG (fluorodeoxyglucose 18F) radiotracer uptake at the medial aspect of the right femoral stem hardware (blue arrow) and less intensely in the surrounding soft tissues, consistent with inflammatory postsurgical changes. (A) Coronal orientation and (B) axial orientation.
