case_images: T1 FSE). The right pedicle was involved, and part of the mass protruded into the spinal canal. The lesion was uniformly enhancing on contrast-enhanced MRI images (Figure 1 D-F). 18F-FDG PET/CT scan showed the expansile bone destruction of the second lumbar vertebra with increased FDG uptake (SUVmax: 11.8) (Figure 2). The cortex was eroded, with a residual bone crest.
