Fig 4. — Case 12.

A, T1-weighted image.

B, T2-weighted image.

C, Gadolinium-enhanced T1-weighted image.

There are 2 levels of trauma. The upper one is an anterior opening fracture at T11–T12 with disk-space widening containing a fluid cavity inside (A, arrow) forming a pseudarthrosis. Erosion and enhancement is present in the adjacent endplates and vertebral bodies extending from the anterior border to the posterior border at this level. There are fractures in the facets, spinous process, and the interspinous space of T10–T11, with hypointensity on T1-weighted and T2-weighted images (A–C, black arrowheads). The postcontrast T1-weighted image (C) shows enhancement along the margin of the fracture line.

The lower level is an anterior wedge deformity of the L2 vertebral body (A, white arrowhead). The L2 vertebral body has no edema, enhancement or cavity inside, and is compatible with an old healed fracture. There is suspicious retrolisthesis of L2 on L3, and L3 on L4. The disk space of L1–L2 and L2–L3 are narrowed, with abnormal signal intensity in the disk space and the adjacent bone marrow from ankylosing spondylitis.

D, E and F, MR imaging 14 months later than A–C show little change.

G and H, Sagittal reformatted CT scan 14 months after A–C in the midline (G) and off midline (H) show the fracture line (arrows) and adjacent bony sclerosis.

I, Conventional radiograph 54 months earlier than A–C shows possible avulsion injury with a teardrop fragment in the anterior inferior T11 vertebral body (white arrow) and reactive hyperostosis at anterior superior corner of T12 vertebral body as a result of AS called “shiny corner” configuration (black arrow). There is squaring of the vertebral bodies and ossification of the ALL in other levels due to AS.
