These vertebrae form the midsection of the cervical spine, near the base of the neck. Presented as an education exhibit at the 2018 RSNA Annual Meeting. Figure 14b. Other procedures may be done to relieve pressure on the spine or repair fractured vertebrae. That out of the, way. C3-C4: There is a mild-to-moderate bilateral C4 foraminal narrowing. Classically, anterior spinal artery infarct produces T2 hyperintensity in the anterior horns and surrounding white matter, forming the owls eye sign (Fig 9). Wear and tear of the spine may take years to cause symptoms. Multiple lesions disseminated over time and space. T2 reflects the length of time it takes for the MR signal to decay in the transverse plane. Sciatica from the S1 nerve root occurs as a result of the compression of the nerve between the L5S1 segments of the spinal cord. It is an unfortunate truth that there are not many options to date to completely recover from a cervical spinal cord injury. (c) Axial CT myelogram shows marked thinning with anterior displacement of the cord at the T3-T4 level (arrow). to the front. For these, please consult a doctor (virtually or in person). (b) On an axial T2-weighted MR image, the lesion is seen to affect nearly the entire cross-sectional volume of the spinal cord without associated expansion (arrow). dAVF usually manifests with poorly defined T2 hyperintensity and cord enlargement, which represent spinal cord edema. The C4 vertebra is located in the neck region of the spinal column, just above the thoracic vertebrae. This vital role means that, even if the rest of your body is functioning perfectly normally, a spinal cord injury can undermine even the most basic functions.

Normally, MS is a somewhat painless disease with symptoms of paresthesias (pins and needles) and sensory change along with balance issues. Please note, we cannot prescribe controlled substances, diet pills, antipsychotics, or other commonly abused medications. (c) Axial fluid-attenuated inversion-recovery (FLAIR) MR image of the brain demonstrates areas of bilateral patchy T2 or FLAIR high SI in a pericallosal and periventricular distribution (arrows). At MRI, there is usually long-segment nonexpansile T2 hyperintensity, which can be seen in all three entities. A cervical vertebrae injury is the most severe of all spinal cord injuries because the higher up in the spine an injury occurs, the more damage that . This diagnostic approach provides a practical framework to aid both trainees and practicing radiologists in workup of myelopathy.

Hemangioblastoma is a well-demarcated highly vascular nonglial tumor (42). Lesions are typically short (ie, <1.5 vertebral body segments) in craniocaudal extent, peripheral, and wedge-shaped or round and affect less than half of the cross-sectional area of the cord (1,12) (Figs 4, 5). Surgical treatments include removing bone spurs and widening the space between vertebrae. as a cause for any neurological deficit. At Another Johns Hopkins Member Hospital: Your thoughts matter to us. Messages also are carried up the spinal cord to the brain so a person can feel sensations. An increase in T2 signal intensity is often associated with chronic compression of the spinal cord, and it is well established that chronic compression results in structural changes to the spinal cord. Figure 10d. Thecal refers to the covering of the spinal cord. Neuromyelitis Optica Spectrum Disorder.NMOSD is a demyelinating disease that predominantly affects the optic nerves and spinal cord, although brain lesions appear to be more common than previously recognized (1,12,19). 2020 Dec 4;99(49):e23098.
