Treatment of cervical spine metastasis with minimally invasive cervical spondylectomy: A case report and literature review

Figure 1 Imaging changes of C4 vertebra before treatment. A: Sagittal computed tomography (CT) showed the metastasis at the C4 vertebral body and cervical kyphosis; B: The coronal CT showed the right vertebral artery (VA) was compressed by the tumor; C: Sagittal magnetic resonance imaging (MRI) showed the lesion protruded into the spinal canal and caused spinal cord compression at the C4 segment; D: Coronal MRI showed the lesion caused spinal cord and right VA compression; E: The three-dimensional printed model shows here the location and extent of the tumor.
