Brain abscess.

Accumulation of pus caused by a bacterial infection of the brain.


It affects all ages. Often, people do not get to find out the primary cause of bacterial infection that causes brain abscess.

Usually the pathogens reach the brain by one of three ways:

For contiguity; infection that extends from the surrounding structures, such as osteomyelitis, mastoiditis or sinusitis.

By direct inoculation; infection caused by a head wound.

By hematic; infection that spreads through the blood supply from other infected organs such as lungs, skin or heart valves.


The following symptoms usually appear along several hours. They are similar to those of a brain tumor or stroke:


Nausea and vomiting.

Weakness, numbness or paralysis on one side of the body.

Step irregular.



Confusion or delirium.

Difficulty speaking.

Diseases of the heart valves, artificial limbs or in them.

Risk Factors.

See your doctor if you have any infection - especially around the nose or face - to prevent it from spreading.

If you are a carrier of artificial heart valves, or is damaged, must follow a protocol to protect antibiotic trivial problems, such as dental manipulations. Check with your doctor.



History and physical examination by a doctor.

Analysis of blood and spinal fluid.


Brain imaging, X - rays through the head, TAC or R. M. N.
