case_images: A 75-year-old man presented to our hospital 3 years ago complained about pain in the left THA for approximately 6 months (Figure 1A). A two-stage reconstruction approach was selected, and the patient received antibacterial-loaded bone cement treatment for 3 months (Figure 1B) before undergoing revision surgery. Bone scans (Figures 1D, E) showed no abnormal uptake in the left THA, while X-rays (Figure 1C) and serological results (WBC: 5.39 109/L, CRP: 1.81 mg/dl, ESR: 10 mm/h, IL-6: 1.5 pg/ml) indicated no apparent abnormalities.

case_images: 68Ga-FAPI PET/CT revealed increased uptake in the right scapular spine (Figure 2A, red arrow, SUVmax: 4.9), and multiple calcified lymph nodes with enhanced uptake in the lung hilum and mediastinum (Figure 2A, yellow arrow, SUVmax: 4.5). Additionally, increased uptake was observed along the iliopsoas around the left hip joint, with an SUVmax of 6.3 (Figures 2A-J).
