Aseptic HLA B27-positive spondylodiscitis: decreased 18F-FDG uptake after etanercept treatment

Abstract: summaryWe observed a 69-year old man suffering from HLA B27 ankylosing spondylitis with persistent night back pain. 18F-FDG-PET/CT showed an increased metabolism at the level of the spinal space of L2-L3, L3-L4 with increased uptake compatible with spondylodiscitis. He started therapy with etanercept 50 mg/week. After six months of treatment repeated testing showed no uptake of the discs and vertebral bodies.

“…It has to be reminded that FDG is not tumour or infective specific [ 69 , 70 ], and it could help in the identification of the right site for biopsy [ 71 , 72 ]. It has to be mentioned that FDG uptake was found in inflammatory and rheumatologic diseases [ 73 , 74 ], such as aseptic spondylodiscitis in a patient with HLA-B27 positive patient [ 74 ]. We always have to remember that FDG is not specific for the presence of microorganism, but the presence of our immune system reaction to external offences and increased metabolism cells, such as tumoral ones.…”
