Exemplary case of a 65-year-old male with PS: CT and MRI demonstrated L2/3 infection (a, b, and c). The SISS was 7, indicating a potentially unstable lesion. Percutaneous pedicle screw fixation was performed. CT imaging at 6 months post-surgery revealed sclerosis at L2/3 and maintained lumbar spine stability without screw loosening (panel d). MRI at 6 months revealed complete resolution of the infection (panels e and f)
