Reason: C4-5 disc herniation s/p MVA History: Neck pain The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. Incidental note is made of partial empty sella.At C2-3 there is no significant compromise to the spinal canal or neural foramina. There is a very small central disk protrusion at this level.At C3-4 there is no significant compromise to the spinal canal or neural foramina. There is a small central disk protrusion at this level.At C4-5 there is redemonstration of a central disk extrusion with extrusion of disk material behind of the C3 vertebral body. There is associated effacement of spinal fluid ventral and posterior the spinal cord and compression of the spinal cord. Relative to the prior exam there is no significant change.At C5-6 there is no significant compromise to the spinal canal or neural foramina. There is a minor disk protrusion at this level.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.
1.There is redemonstration of a large central disk extrusion at C4-5 which compresses the spinal cord and creates spinal stenosis. This has not changed substantially compared to the previous exam.2.There is degenerative disk disease also present at other levels.
