This is the most common cause of syringomyelia, where the anatomic abnormality, which may be due to a small posterior fossa, causes the lower part of the cerebellum to protrude from its normal location in the back of the head into the cervical or neck portion of the spinal canal. A syrinx may then develop in the cervical region of the spinal cord.
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
Myelomalacia is a pathological term referring to the softening of the spinal cord. [1] Possible causes of myelomalacia include cervical myelopathy, hemorrhagic infarction, or acute injury, such as that caused by intervertebral disc extrusion.
Syringomyelia is often associated with type I Chiari malformation and is commonly seen between the C-4 and C-6 levels. The exact development of syringomyelia is unknown but many theories suggest that the herniated tonsils in type I Chiari malformations cause a "plug" to form, which does not allow an outlet of CSF from the brain to the spinal canal.
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
A fluid-filled lesion forms, known as a syrinx. [1] This can vary in size significantly between patients. [1] Nerve fibres may be compressed where they cross the midline, or in other parts of the spinal cord. [1] Cranial nerves may be affected. [3] Syringobulbia may be associated with syringomyelia, a syrinx limited to the spinal cord. [4]
In adults, surgery to detether (free) the spinal cord can reduce the size and further development of cysts in the cord and may restore some function or alleviate other symptoms. Although detethering is the common surgical approach to TCS, [ 25 ] another surgical option for adults is a spine-shortening vertebral osteotomy .
