A Rare Case of Acute-Onset Spastic Quadriparesis Caused by a Chondroma of the Cervical Spine

Figure 1

Magnetic resonance images (MRIs) and computed tomography scans (CTs) acquired at the time of acute onset of quadriparesis (a-f) and MRIs acquired 2 years earlier the quadriparesis (g, h): (a) sagittal T1WI, (b) axial T1WI, (c) sagittal T2WI, (d) axial T2WI, (e) sagittal CT, (f) axial CT, (g) sagittal T2WI, and (h) axial T2WI. Images at the onset shows a mass in the spinal canal at C4-5 on the right that is compressing the spinal cord. CT indicates that the mass did not contain osseous tissue. On the other hand, MRIs acquired 2 years earlier to investigate neck pain show that the tumor was present at that time but was not large or compressing the spinal cord.
