Draining pus out of a brain abscess!
Brain or cerebral abscess is caused by intracranial inflammation with subsequent abscess formation, which is a pus-filled swelling in the brain that commonly occur when bacteria (usually polymicrobial with streptococcus being the most common) or fungi reaches and infects part of the brain.
Abscesses can originate from infection of contiguous structures (eg, otitis media, dental infection, mastoiditis, sinusitis) secondary to hematogenous spread from a remote site (especially in patients with cyanotic congenital heart disease), after skull trauma or surgery, and rarely, following meningitis.
As a result, swelling and irritation (inflammation) develops.
It is regarded as a medical emergency and immediate surgical drainage of the abscess provides the most optimal therapy. The procedures used are aspiration through a bur hole and complete excision after craniotomy. These procedures are also diagnostic and provide material that can guide antimicrobial therapy.
Needle aspiration is the preferred and the most commonly used procedure, seen in the video above.
