Fig. 2

Giant cell tumor originating from the L1 vertebral body. a Axial computed tomography (CT), b reformatted sagittal plane, c sagittal plane T1-weighted image, d sagittal plane T2-weighted image, and e sagittal short time inversion recovery (STIR) image. a The lesion invaded the left pedicle with marginal sclerosis and invaded the right transverse process with an ill-defined margin. b The lesion invaded the anteroposterior L1 vertebral body with a well-defined margin. The lesion showed an intermediate signal intensity in T2-weighted image (T2WI) and STIR, while the mass compressed the dural sac and invaded the L1 vertebral body.
