Syringomyelia

Syringomyelia

Syringomyelia is a condition where a fluid-filled cyst (syrinx) forms within the spinal cord. Over time, this cyst expands and compresses the spinal cord tissue, leading to various neurological problems.

Characteristics

  • The syrinx typically starts in the cervical (neck) spinal cord but may extend along the entire spinal cord.

  • The growth of the cyst disrupts the function of the spinal cord nerves.

Causes

  • Chiari Malformation Type I (one of the most common causes)

  • Spinal cord trauma

  • Spinal cord tumors

  • Infections like meningitis

  • Idiopathic syringomyelia (in some cases, the cause is unknown)

Symptoms

  • Loss of sensation in the shoulders and arms (especially decreased sensation to pain and temperature)

  • Muscle weakness and atrophy (wasting) in the hands

  • Back and neck pain

  • Spasticity (muscle stiffness)

  • Bladder and bowel control problems

  • Difficulty walking

Diagnosis

  • Magnetic Resonance Imaging (MRI): Shows the fluid-filled cyst within the spinal cord.

  • Underlying causes, such as Chiari malformation or tumors, can also be detected via imaging.

Treatment

  • Treatment of underlying causes: For example, decompression surgery for Chiari malformation.

  • Direct interventions: Draining the syrinx or placing a shunt to reduce pressure on the spinal cord.

  • In mild or non-progressive cases, regular monitoring may be recommended.

Outcome

  • Early treatment can stop or slow the progression of the disease. In advanced cases, nerve damage may be permanent.
