Cervical spondylotic myelopathy with syringomyelia presenting as hip Charcot neuroarthropathy: A case report and review of literature

Figure 1 Magnetic resonance imaging of the cervical spine. Cervical syringomyelia at C4 (white arrow); cervical disc herniation and spinal stenosis from the C3 to C7 Levels.

Figure 2 Computed tomography of the cervical spine. A: C4 vertebral body destruction; B: C5-7 vertebral body assimilation.

Figure 3 Right hip joint. A: Computed tomography (CT) three-dimensional reconstruction; B: CT; C: X-ray. Joint space loss, articular surface collapse, and destructive acetabulum and femoral head changes; D: Right hip magnetic resonance imaging, T2W1. Articular cartilage loss, joint degeneration, soft tissue disorder, and obvious joint fluid were observed.

Figure 5 Pathological results. A: Right femoral head tissue sections during surgery. Tissue degeneration, calcification, small vascular proliferation and a multicore giant cell response in some regions; B: Synovial tissue sections of the right hip joint during the operation. Capillary hyperplasia was accompanied by infiltration of acute chronic inflammatory cells, local region tissue denaturation and calcification.

Figure 6 Follow-up right hip X-ray film 6 mo after total hip arthroplasty. X-rays revealed that the acetabular inclination and anteversion were well maintained and showed signs of periprosthetic bone growth without clinical manifestations of implant loosening compared with postoperative observations.
