Spinal intraosseous schwannoma without spinal canal and neuroforamina involvement: A case report

Figure 1 Imaging findings before treatment. A: Cervical X-ray showed loss of height of the seventh cervical (C7) vertebral body; B: Sagittal T2-weighted magnetic resonance imaging of the cervical spine showing a hyperintense prevertebral mass; C: Axial magnetic resonance imaging showed a well-demarcated lesion seemingly originating in corpus C7 without spinal canal and neuroforamina involvement; D: Axial computed tomography (CT) shows lytic changes in the anterior cortical margin of C7 body. Posterior cortical margin is intact; E: CT scanning exhibited a bony defect of the C7 body; F: Three-dimensional CT reconstruction shows a circular defect in the anterior edge of the C7 vertebra.
