case_images: This diagnosis was confirmed by an MRI scan of the dorsolumbar spine, showing an edema of the L2-L3 vertebral endplates associated with inflammatory infiltration of the right and left anterior and lateral paravertebral soft tissues at L2-L3 and an anterior epiduritis of L3-L4 (Fig. 2). When the antibiotic treatment was stopped, the PET-scanner showed erosive lesions on the L2 and L3 plateaus, which appeared to be sequelae of the spondylodiscitis, as did the follow-up MRI (Fig. 2).
