Although brain abscess is relatively rare, it is a complication encountered increasingly in patients whose immune systems have been suppressed either through therapy or disease.
Pathophysiology
A brain abscess is a collection of infectious material within the tissue of the brain. It may occur by direct invasion of the brain from intracranial trauma or surgery; by spread of infection from nearby sites, such as the sinuses, ears, and teeth (paranasal sinus infections, otitis media, dental sepsis); or by spread of infection from other organs (lung abscess, infective endocarditis) (Hickey,2003). To prevent brain abscess, otitis media, mastoiditis, sinusitis, dental infections, and systemic infections should be treated promptly.
Symptoms of Brain Abscess
Symptoms may develop slowly, over a period of 2 weeks, or they may develop suddenly.
They may include:
