case_images: Pre-treatment magnetic resonance imaging (MRI). (A) Sagittal T2 cervical spine shows high signal T2-T5. (B) Diffusion-weighted imaging (DWI) shows restricted diffusion within the gray matter. (C) Axial T2 suggests a high signal centrally in the spinal cord. (D) CT of the sacroiliac joint shows bilateral sacroiliitis and calcification of the anterior and posterior longitudinal ligaments.

case_images: Diffusion-weighted imaging (DWI) with an apparent diffusion coefficient showed restricted diffusion, which can be seen in patients with acute ischemia (Figures 1A-C). CT of the sacroiliac joint showed that he had bilateral sacroiliitis and calcification of the anterior and posterior longitudinal ligaments (Figure 1D).
case_images: MRI of this patient after therapy. (A) Thoracic kyphosis with multiple vertebral wedgies at T4, T6, T7, T9, L1, and L3. (B) Sagittal T2 thoracic vertebrae T2-T5 are slightly hypersignal. (C) DWI shows a slightly elevated signal in the gray matter. (D) Axial T2 central hypersignal is less than before.

case_images: Due to his AS, the patient had spinal deformities, ligament ossification, and spinal space occlusion (Figure 2A), which made lumbar puncture technically challenging. AS. After 2 weeks, a thoracic spine MRI showed a slightly decreased signal (Figures 2B-D).
