case_images: Magnetic resonance images of the patient before admission. The red pentagrams indicate the lesion mimicking ModicIchanges, which are hypointense on T1-weighted sequences (A), hyperintense on T2-weighted sequences (B) and STIR sequences (C) Yellow arrows show inhomogeneous signal in the disc space at T12/L1 in keeping with discitis (D,E).

case_images: At the initial visit, the patient only had magnetic resonance imaging (MRI) data from a different hospital, which showed endplate erosion and damage to intervertebral disks (Figure 1).
case_images: X-ray and CT three-dimensional reconstruction of thoraco-lumbar vertebrae after admission. Anterior and lateral radiographs (A,B) show abnormal paravertebral and anterior longitudinal ligament ossification. Flexion and extension lateral radiographs (C,D) represent a loss of lumbar mobility. Sagittal, coronal, and reconstructed coronal CT images (E-H) demonstrate instability of the lumbar spine result from no bone bridging between T12 and L1.

case_images: Based on imaging (CT and radiography) findings (Figure 2), medical history, and clinical examination, we performed an HLA-B27 blood test to confirm the diagnosis of AS with an AL.
case_images: Preoperative 3D model printing and intraoperative fluoroscopic images. Anterior (A), lateral (B), and posterior (C) view of the 3D printed model. Intraoperative anterior and lateral radiographs (D,E) demonstrate the proper position for the diseased lesion using location-needle. Anterior and lateral radiographs (F,G) of excellent fusion cage and percutaneous pedicle screws placement is seen.

case_images: Then, eight PPSs were inserted (Figure 3).
case_images: Postoperative immediate CT images and wound scars after minimally invasive surgery of LIF. Postoperative CT images (A-C) show good positioning of the internal fixation and normal sagittal sequence of the lumbar spine. Eight minimally invasive incisions (D) for internal fixation and fusion surgery.

case_images: Compared with traditional open surgery, this surgical method had less blood loss and smaller incision wounds, which resulted in a faster recovery (Figure 4).
