Syringomyelia (sear-IN-go-my-EEL-ya) is a disorder in which a fluid-filled cyst forms within the spinal cord. This cyst, called a syrinx, expands and elongates over time, damaging the spinal cord. Since the spinal cord connects the brain to nerves in the extremities, this damage may cause pain, weakness, and stiffness in the back, shoulders, arms, or legs. Symptoms vary among individuals. Other symptoms may include headaches and a loss of the ability to feel extremes of hot or cold, especially in the hands. Signs of the disorder tend to develop slowly, although sudden onset may occur with coughing or straining. If not treated surgically, syringomyelia often leads to progressive weakness in the arms and legs, loss of hand sensation, and chronic, severe pain. In most cases, the disorder is related to a congenital abnormality of the brain called a Chiari malformation, which causes brain tissue to protrude from its normal location in the back of the head and into the cervical or neck portion of the spinal canal. Syringomyelia may also occur as a complication of trauma, inflammation, spinal cord injury, hemorrhage, spinal cord tumors, or other conditions. Symptoms may appear months or even years after the initial injury, starting with pain, weakness, and sensory impairment originating at the site of trauma. Some cases of syringomyelia are familial, although this is rare.

Syringomyelia is a condition in which a cyst, called a syrinx, forms within the spinal cord. This cyst expands and elongates over time, destroying the center of the spinal cord which can result in pain, weakness, stiffness in the back, shoulders, arms, or legs, headaches, and insensitivity to temperature (especially in the hands). Symptoms vary from person to person. Syringomyelia is often related to a congenital abnormality of the brain called a Chiari I malformation, but may also occur as a complication of trauma, inflammation of the tissue that surrounds the brain and spinal cord (meningitis) such as the inflammation of the arachnoides (arachnoiditis), hemorrhage, or a tumor. Symptoms may appear months or even years after the initial injury. Some cases of syringomyelia are familial, although this is rare.
Treatment often involves surgery and avoiding activities that involve straining. Drainage of the cysts using a catheter, drainage tubes, and valves may be required in some patients. If not treated, the disorder can lead to progressive weakness in the arms and legs, loss of hand sensation, and chronic, severe pain.

Syringomyelia is a rare disorder that causes a cyst to form in your spinal cord. This cyst, called a syrinx, gets bigger and longer over time, destroying part of the spinal cord. Damage to the spinal cord from the syrinx can cause symptoms such as
Pain and weakness in the back, shoulders, arms or legs
Headaches
Inability to feel hot or cold
Symptoms vary according to the size and location of the syrinx. They often begin in early adulthood.
Syringomyelia usually results from a skull abnormality called a Chiari I malformation. A tumor, meningitis or physical trauma can also cause it. Surgery is the main treatment. Some people also need to have the syrinx drained. Medicines can help ease pain. In some cases, there are no symptoms, so you may not need treatment.
