Spinal cord cavitation is a progressive degenerative disease of the spinal cord due to various causes of the spinal cord, characterized by dilatation of the central canal of the spinal cord filled with cerebrospinal fluid, and is most often seen between the ages of 10 and 60. It can have a variety of causes, such as congenital anomalies, such as malformations, or spinal cord injury, when the injury results in a cavity in the spinal cord, or tumors or occupational lesions that cause abnormalities in the cerebrospinal fluid circulation, resulting in a cavity in the central canal. Inflammatory conditions, such as bacterial and tuberculous subarachnoiditis, are also seen, as are other causes. For spinal cord cavitation, it mainly produces a series of neurological symptoms, such as pain, weakness of the lower extremities, abnormal sensation, atrophy, spasticity, and dysfunction of urination and defecation, and generally rarely causes fatal corresponding conditions. The prognosis for spinal cord cavitation is mostly good and rarely fatal if there are symptoms and symptoms that can be partially improved with surgery.
