Abstract
in English, Turkish

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 ¹⁸fluorine-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) to rule out a spondylodiscitis. No sign of spondylodiscitis was found on ¹⁸F-FDG PET/CT, but images revealed an increased ¹⁸F-FDG uptake in HO areas, matching with ongoing osteoblastic activity on a following bone scan.

On ay önce omurilik yaralanmasını takiben sol kalça çevresindeki kaslarda nörojenik heterotopik ossifikasyon (HO) öyküsü olan 54 yaşında bir erkek hasta, spondilodiskiti ekarte etmek için ¹⁸flor-florodeoksiglukoz (¹⁸F-FDG) pozitron emisyon tomografisi/bilgisayarlı tomografi (PET/BT) için nükleer tıp merkezimize sevk edildi. ¹⁸F-FDG PET/BT’de spondilodiskit belirtisi bulunmadı, ancak görüntüler, sonraki kemik taramasında devam eden osteoblastik aktivite ile eşleşen, HO alanlarında ¹⁸F-FDG tutulumunun arttığını ortaya koydu.

Keywords: 18F-FDG PET/CT; Heterotopic ossification; bone scan.
