Brain Abscess

Prevention of brain abscess

Vaccinations availble for a number of the causative pathogens. However you cannot specifically vacinate against brain abscesses.

Treatment of brain abscess

The treatment will depend on the size and number of brain abscesses present.

Small abscesses that are less that 2.5 cm (0.98 inches) can usually be treated by administering antibiotics, antiviral or anti-fungal medication intravenously (directly into the vein).

If the abscess is larger then 2.5cm, it is usually necessary to drain the pus out of the abscess (aspiration) or cut the abscess out of the healthy tissue (excision).

If there are multiple abscesses, it is usually thought too risky to cut them all out, so aspiration is usually recommended.

Aspiration and excisions are usually carried out using a surgical procedure known as a craniotomy.

Intravenous medication is also used in combination with surgery to accelerate the recovery process.

The original infection that led to your brain abscess will also need to be treated. This can usually be done through the use of medication.

During a craniotomy, the surgeon will shave a small section of your hair, and then remove a small piece of bone, to gain access to your brain.

The abscess with then be drained of pus, or totally removed. A CT scanner may be used during the operation, so the surgeon can more accurately locate the exact position of the abscess.

Once the abscess has been treated, the bone is replaced, and held in position with stitches and then allowed to heal.

Antibiotic therapy:

The choice of antibiotic will be specific defined by the organism that caused the brain abscess.
