Metabolic Activity of Neurogenic Heterotopic Ossification on 18 F-FDG PET/CT Matching with Ongoing Osteoblastic Activity on Bone Scan

[摘要] A 54-year-old man, with previous history of neurogenic heterotopic ossification (HO) in muscles around the left hip following a spinal cord injury ten months earlier, was referred to our nuclear medicine center for an 18 fluorine-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) to rule out a spondylodiscitis. No sign of spondylodiscitis was found on 18 F-FDG PET/CT, but images revealed an increased 18 F-FDG uptake in HO areas, matching with ongoing osteoblastic activity on a following bone scan.
