In an epidural abscess, pus accumulates in the area between the outermost layer of the spinal cord and the surrounding vertebrae, a serious medical condition. Compression of the spinal cord and nerve roots can result in neurological deficits and potentially life-threatening complications. In this article, you will learn about epidural abscess, its causes, symptoms, diagnosis, treatment, and prevention.
Causes
Bacterial infections are the most common cause of epidural abscesses. Staphylococcus aureus, Streptococcus species, and Escherichia coli are the most common bacteria associated with epidural abscesses. There are several ways in which these bacteria can enter the epidural space, including bloodstream infections, direct spinal trauma or surgery, or adjacent infections from nearby structures, such as the skin or soft tissues.
Symptoms
An epidural abscess may cause a variety of symptoms, depending on the location and extent of the infection. Common symptoms include:
-
Back pain that worsens with movement or palpation.
-
Deficits in the nervous system, such as weakness, numbness, or tingling.
-
Systemic infections are characterized by fever, chills, and other symptoms.
-
Inability to control bladder or bowel movements.
-
Balance or walking difficulties.
-
Affected area of the spine may be tender or swollen.
Diagnosis
An epidural abscess is typically diagnosed with a combination of clinical evaluation, imaging studies, and laboratory tests. Physical examinations can be used to evaluate neurological function and identify signs of inflammation or tenderness in the spine. A magnetic resonance imaging (MRI) or computed tomography (CT) scan can provide detailed images of the spine and help visualize an abscess. The causative bacteria may be identified and signs of infection assessed by laboratory tests, including blood cultures and cerebrospinal fluid analysis (CSF).
Treatment
It is usually recommended to treat epidural abscesses with antibiotics and surgery. The primary goal of treatment is to eliminate the infection, relieve spinal cord compression, and prevent neurological complications. The following treatment options may be available depending on the severity of the infection and the presence of neurological deficits:
-
To control the spread of infection, intravenous antibiotics target the causative bacteria.
-
A surgical drainage or decompression is performed to remove the abscess and relieve pressure on the spinal cord or nerve roots.
-
In order to promote recovery and restore function, supportive care measures, such as pain management and physical therapy, are necessary.
Prevention
The prevention of epidural abscess involves minimizing the risk of bacterial infections leading to spinal abscess formation.
-
To reduce the risk of skin and soft tissue infections, practice good hygiene and wound care.
-
Treatment of spine and adjacent structures infections or injuries as soon as possible.
-
Sterile techniques should be used during invasive spinal procedures or surgeries.
-
Exercise, a balanced diet, and adequate rest are essential to maintaining a healthy immune system.
As a result of the accumulation of pus in the epidural space of the spine, epidural abscesses are serious medical conditions. In order to recognize and manage this potentially life-threatening condition promptly, it is essential to understand its causes, symptoms, diagnosis, treatment, and prevention.
