Compressive myelopathy

Case contributed by Dr Bruno Di Muzio
MRI

Cervical spine has lost the normal physiological lordosis and has a straight vertebral body alignment. There are loss of cervical disc sign on T2 inferring dehydration. C5/6: Moderate right paramedian disc protrusion indents the spinal cord anteriorly, with normal cord signal maintained. Mild stenosis of the right intervertebral foramen. C6/7: Moderate central disc protrusion indents the spinal cord anteriorly, especially with a left paramedian disc extrusion component, associated with high cord signal on T2. Mild stenosis of the intervertebral foramina.

Annotated image

Yellow arrow showing the spinal cord myelopathy characterised by increased signal on T2/STIR at the level of C6/7 disc (sagittal images on the left). Axial images on T2 and STIR demonstrate disc protrusion with an extrusion component at C6/7 level. Left parasagittal image delineating the extrusion component. 

Case Discussion

Cervical cord compressive myelopathy is caused by narrowing of the sagittal diameter of the spinal canal secondary to congenital, degenerative or traumatic changes in the cervical spine.
