Patient (case # 14) with a history of hip prosthesis implantation performed 8 months before imaging. The results of 18F-FDG PET/CT (upper row) and 68Ga-citrate PET/CT (lower row) are presented. ad The green arrows indicate an increased 18F-FDG uptake occurring in necrotic tissue located within a swollen left quadratus femoris muscle. There was also evidence of an increased 18F-FDG uptake occurring at the bone-prosthesis interface (cup component; blue arrow). Taken together, these findings were suggestive of an infectious process which was confirmed intraoperatively (presence of cloudy synovial fluid and necrotic tissue). eh The blue arrows indicate an increased 68Ga-citrate uptake occurring at the bone-prosthesis interface (especially in the proximal portion). An osteolytic change in the anterior cortex of the left femur was observed on a CT image, accompanied by an increased 68Ga-citrate uptake (which was present in the adjacent bone marrow as well, red arrows)
