Fig. 1. Magnetic resonance images (A: T2-weighted images, B: T1-weighted images, C: Enhanced sagittal T1-weighted images, D: Enhanced axial T1-weighted images). They demonstrate progressive collapse of the previously augmented L1 vertebra. They also demonstrate a new compression fracture at T12 (large arrow), paravertebral abscess, and spondylitis of T12 and L1 (small arrow).
