A brain abscess is an infection, a collection of purulent material in the cerebral hemispheres, which behaves clinically as an intracranial mass.
Intracranial pressure can increase excessively and compromise the patient's life.
A brain abscess is a medical emergency and hospital admission is often necessary until the necessary treatment is performed and the disease is stabilized.
It is more common in males and the most common isolated agents are streptococcus and staphylococcus, which are usually multibacterial.
