What causes a cyst on the spinal cord?

The cause of spinal cysts is unknown, but they may result from degeneration and instability of the spine in areas subjected to repetitive motion, particularly the joints in the lumbar region. Patients with spinal cysts may have other degenerative conditions of the spine, such as arthritis and disk disease.

What is conus medullaris anatomy?

Anatomical terminology The conus medullaris (Latin for “medullary cone”) or conus terminalis is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower.

What level is the conus medullaris at?

The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult.

Can a spinal cyst be drained?

Additional doses may be required over time. Another method of treating spinal synovial cysts is to drain the cyst using a small needle. This reduces the cyst size and relieves nerve pressure, but the needle may damage nerves near the spinal canal.

Can synovial cyst cause back pain?

Synovial cysts of the spine aren’t deadly or cancerous and often don’t produce symptoms. Symptoms that may occur include back pain or numbness, tingling, or cramping in the legs. There are treatments to help reduce discomfort, such as medication, activity modification, and injections.

What does conus medullaris do?

The conus medullaris give rise to the lumbar sympathetic, sacral somatic and sacral parasympathetic nerves which continue downward within the cauda equina. These nerves have important functions which can be impaired by injury or ischemia.

What causes conus medullaris?

The potential causes of conus medullaris syndrome are: Severe trauma to the lower back such as a gunshot wound, hard blow, or involvement in a car accident. Spinal cord infections. Spinal tumors.

Where does conus medullaris start?

The lowermost tapering extremity of the spinal cord is called the conus medullaris, which is around the first or second lumbar vertebra and can sometimes be lower.

Should a cyst on the spine be removed?

Synovial cysts develop in joints in your spine and, though they’re benign, they can grow large enough to pinch spinal nerves. The physicians at Spinetech offer a range of interventional treatments to manage your pain without surgery, but when your symptoms worsen, synovial cyst removal is the best option.

How do they remove a cyst from your spine?

To remove the cyst and relieve pressure on the spinal cord or spinal nerves your doctor will perform a procedure called microdecompression. This is often followed by fusion of the adjacent vertebrae to avoid recurrence of the cyst.
