Spinal Cord Abscess
Multimedia
Definition
Spinal cord abscess is swelling and irritation (inflammation) and the collection of infected material (pus) around the spinal cord.
Alternative Names
Abscess - spinal cord
Causes, incidence, and risk factors
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 an epidural abscess.
Pus forms as a collection of:
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 it 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 of a spinal cord abscess:
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.
The disorder is rare, but may be life-threatening.

Symptoms
Signs and tests
A physical exam often shows tenderness over the spine. An exam may show signs of:
Paralysis of the lower body (paraplegia) or of the entire trunk, arms, and legs (quadriplegia)
Changes in sensation below the area of involvement
The amount of nerve loss depends on where the lesion is located on the spine and how much it is compressing the spinal cord.
Tests that may be done:
Gram stain and culture of abscess material

Treatment
The goals of treatment are to relieve pressure on the spinal cord and cure the infection.
Urgent surgery to relieve the pressure is sometimes recommended. The surgery is called laminectomy. It involves removing part of the spine bone and draining the abscess. Sometimes it is not possible to completely drain the abscess.
Medicines are prescribed to get rid of the infection. This may include a combination of antibiotics.
Corticosteroids may occasionally be prescribed to reduce swelling and pressure on the spinal cord.
Expectations (prognosis)
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.
Complications
The abscess can either injure the spinal cord from direct pressure, or it can cut off the blood supply to the spinal cord.
Complications may include:
Calling your health care provider
Go to the emergency room or call the local emergency number (such as 911) if you have symptoms of spinal cord abscess.

Prevention
Thorough treatment of boils, tuberculosis, and other infections decreases the risk.
People with endocarditis or congenital heart disorders may need to take preventive antibiotics before having dental or other mouth procedures.
