Figure 2

clinical synopsis of a 10 years old girl with a history of back pain. Technetium 99m-MDP bone scan (figure 2a and b) shows the rib and multiple osseous spine lesions at diagnosis. Initial magnetic resonance imaging (MRI) revealed a compression of vertebra #9 and 11 (figure 2c: T1-weighted sagittal image (arrows); figure 2d: T1-weighted sagittal image after i.v. gadolinium enhancement), in addition to oedematous changes predominantly in the 8^th vertebra (figure 2e: strongly T2-weighted sagittal image; arrow). Subsequent MRI 12 months later no longer showed oedematous changes, however the vertebral compressions were still present (figure 2f: T1-weighted sagittal image (arrows); figure 2g: T1-weighted sagittal image after i.v. gadolinium enhancement; figure 2h: strongly T2-weighted sagittal image).
