Brain and Spinal Tuberculosis
Tuberculosis (TB) Meningitis and brain abscess are both serious neurological conditions, but they differ in their causes, symptoms, and treatment.
Brain Tuberculosis
Definition
Tuberculous meningitis is the most common form of CNS TB, where the infection spreads to the membranes surrounding the brain and spinal cord.
Causes
Typically caused by *Mycobacterium tuberculosis*, the bacterium responsible for TB, which can spread to the brain from other infected sites in the body.
Symptoms
- Gradual onset of headaches, fever, and neck stiffness.
- Altered mental status, confusion, seizures, and neurological deficits.
Diagnosis
- Lumbar puncture to analyze cerebrospinal fluid (CSF), showing elevated white blood cells and low glucose levels.
- Imaging studies like MRI or CT scans to identify any associated complications (e.g., tuberculomas).
Treatment
- Long-term antibiotics (typically a combination of isoniazid, rifampicin, pyrazinamide, and ethambutol) for at least 6-12 months.
- Corticosteroids may be used to reduce inflammation.
Spinal Tuberculosis
Definition
Also known as Pott's disease, spinal tuberculosis affects the vertebrae and can lead to deformities and neurological complications.
Causes
Often arises from the spread of TB from the lungs or other parts of the body to the spine.
Symptoms
- Back pain, stiffness, and deformity (like kyphosis).
- Neurological symptoms if the spinal cord is compressed, including weakness or numbness in the limbs.
Diagnosis
- MRI or CT scans to visualize abscesses or vertebral collapse.
- Biopsy may be performed to confirm the presence of Mycobacterium tuberculosis.
Treatment
- Similar to brain TB, involves long-term antibiotic therapy for several months.
- Surgery may be necessary to decompress the spinal cord or stabilize the spine in severe cases.
Summary
Both brain and spinal tuberculosis are serious manifestations of TB that require immediate medical attention. Diagnosis involves a combination of imaging and laboratory tests, while treatment typically includes long-term antibiotic therapy. Early detection and comprehensive treatment are crucial to prevent severe complications and improve outcomes.
