Spinal astrocytoma occurs most frequently in young males (mean age of presentation, 29 years) and is associated with neurofibromatosis type 1 (42). When the abnormal cord signal is present in equal or less than 2 contiguous vertebral bodies, a short-segment myelopathy is considered. If the spinal roots below the conus medullaris are involved, . FINDINGS: The cervical vertebral column is straightened. You mention that there are a number of things that could cause abnormal signal. The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone). Spinal cord SI abnormality at MRI is a commonly encountered finding in spinal cord disease and poses diagnostic challenges owing to the broad differential diagnosis and variable appearances at imaging.
