Associated signs include a lack of epidural fat at the posterior wall of the vertebral body, the presence of radicular cysts, [18] anterior meningoceles, nerve root sleeve herniation and gradual erosion of the vertebral bodies (scalloping). [19]
Spinal cord injuries can be divided into categories: complete transection, hemisection, central spinal cord lesions, posterior spinal cord lesions, and anterior spinal cord lesions. Scalloping vertebrae is the increase in the concavity of the posterior vertebral body. It can be seen on lateral X-ray and sagittal views of CT and MRI scans.

It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra. The dura is pierced with a needle during a lumbar puncture (spinal tap).
Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim's disease, [2] [3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
Since the vertebral body in a retrolisthesis moves in a posterior direction, the grading used for spondylolistheses is of little use. It is however useful to divide the anterior to posterior dimension of the intervertebral foramina (IVF) (4) into four equal units. A posterior displacement of up to ¼ of the IVF is graded as Grade 1, ¼ to ½ as ...
The injury is a result of disruption of the stabilizing ligaments between the occiput, or posterior skull base, and the C1 vertebral body, otherwise known as the atlas. The diagnosis is usually suspected by history and physical exam, but confirmed by imaging, typically by CT due to its faster speed in the acute trauma setting, although MRI can ...
In radiology, a Romanus lesion is the erosion of the anterior and posterior vertebral endplates in patients with an inflammatory spondyloarthropathy – such as ankylosing spondylitis or an enteropathic arthropathy.
