FDG uptake in cervical facet subchondral cysts demonstrated by PET/CT.
F-18 fluorodeoxyglucose (FDG) uptake in facet joints related to degenerative disease has been previously described. However, FDG uptake in subchondral cysts is the subject of this report. We describe 2 cases of intense focal FDG uptake in subchondral cysts in the cervical facets seen on positron emission tomography/computed tomography (PET/CT) exams. The location of these cysts immediately adjacent to the facet joints and the presence of associated facet joint degenerative changes are helpful in distinguishing this uptake from metastatic disease or other bone lesions.
