Tenosynovial giant cell tumor involving the cervical spine: A case report

Figure 1 Preoperative X-ray, computed tomography, and magnetic resonance imaging images. A: Plain X-ray of the cervical spine showing destructive lesions (orange arrow) in the appendage area of the C4-5 vertebras; B: Plain computed tomography (CT) of the cervical spine showing bone destruction (orange arrow) and a soft tissue mass in the appendage area of the C4-5 vertebras; C: CT three-dimensional imaging of the cervical spine showing the outline of bone destruction (orange arrow) in the appendage area of C4-5; D: Magnetic resonance imaging showing bone destruction and soft tissue formation (orange arrow) in the C4-C5 accessory region, suggesting the possibility of an invasive, benign bone tumor (e.g., osteoblastoma), and significant compression of the spinal cord and stenosis at the corresponding plane.
