Figure 1 Imaging examinations. A: Initial magnetic resonance imaging (MRI) depicting bone-marrow edema (BME) on the iliac side of the sacroiliac joint and a small stress fracture of the left sacral wing (arrow); B and C: Spine MRI demonstrating reduced vertebral height with normal signal intensity of vertebral bodies, multifocal BME of the posterior elements (arrows) (B) and pannus formation around the dens, suggesting inflammatory spondyloarthropathy (arrow) (C); D and E: X-ray and spinal MRI showed progressive ossification and fusion of the cervical spine and occiput (arrows) with pseudoarthrosis at the C6-C7 level (open arrow); F: Whole-body MRI depicting further progression of fusion of posterior elements of the spine (arrows); G: Prolapse of the C6-C7 intervertebral disk (arrows), at the level of pseudoarthrosis; H and I: Multiple areas of BME in the peripheral skeleton with periphyseal distribution (arrows).
