What are the causes of Spinal Cord Abscess?

A spinal cord abscess is caused by an infection inside the spine. An abscess of the spinal cord itself is very rare. A spinal abscess usually occurs as a complication of an epidural abscess.

Pus forms as a collection of:

  • White blood cells
  • Fluid
  • Live and dead bacteria or other microorganisms
  • Destroyed tissue cells

The pus is commonly covered by a lining or membrane that forms around the edges. The pus collection causes pressure on the spinal cord.

The infection is usually due to bacteria. Often it is caused by a staphylococcus infection that spreads through the spine. It may be caused by tuberculosis in some areas of the world, but this is not as common today as it was in the past. In rare cases, the infection may be due to a fungus.

The following increase your risk for a spinal cord abscess:

  • Back injuries or trauma, including minor ones
  • Boils on the skin, especially on the back or scalp (rare)
  • Complication of lumbar puncture or back surgery
  • Spread of any infection through the bloodstream from another part of the body (bacteremia)
  • Injecting drugs

The infection often begins in the bone (osteomyelitis). The bone infection may cause an epidural abscess to form. This abscess gets larger and presses on the spinal cord. The infection can spread to the cord itself.

A spinal cord abscess is rare. When it does occur, it can be life threatening.

What are the symptoms of Spinal Cord Abscess?

Symptoms may include any of the following:

  • Fever and chills.
  • Loss of bladder or bowel control.
  • Loss of movement of an area of the body below the abscess.
  • Loss of sensation of an area of the body below the abscess.
  • Low backache, often mild, but slowly gets worse, with pain moving to the hip, leg, or feet. Or, pain may spread to the shoulder, arm, or hand.

What are the current treatments for Spinal Cord Abscess?

The goals of treatment are to relieve pressure on the spinal cord and cure the infection.

Surgery may be done right away to relieve the pressure. It involves removing part of the spine bone and draining the abscess. Sometimes it is not possible to drain the abscess completely.

Antibiotics are used to treat the infection. They are usually given through a vein (IV).

What is the outlook (prognosis) for Spinal Cord Abscess?

How well a person does after treatment varies. Some people recover completely.

An untreated spinal cord abscess can lead to spinal cord compression. It can cause permanent, severe paralysis and nerve loss. It may be life threatening.

If the abscess is not drained completely, it may return or cause scarring in the spinal cord.

What are the possible complications of Spinal Cord Abscess?

The abscess can injure the spinal cord from direct pressure. Or, it can cut off the blood supply to the spinal cord.

Complications may include:

  • Infection returns
  • Long-term (chronic) back pain
  • Loss of bladder/bowel control
  • Loss of sensation
  • Male impotence
  • Weakness, paralysis
When should I contact a medical professional for Spinal Cord Abscess?

Go to the emergency room or call the local emergency number (such as 911), if you have symptoms of spinal cord abscess.

How do I prevent Spinal Cord Abscess?

Thorough treatment of boils, tuberculosis, and other infections decreases the risk. Early diagnosis and treatment are important to prevent complications.

Prospective Analysis of Spinal Epidural Abscess Associated Outcomes at the University of Kentucky

Summary: This is a prospective study involving all patients treated at the University of Kentucky for spinal epidural abscess over a 2-year period. Based on ongoing referrals of patients with SEA, we expect that 200 patients will be enrolled during this time window. We propose to study all available clinical, pathological, radiological, and socioeconomic data of patients diagnosed with a spinal infection w...
