Summary

A brain abscess is a pus-filled mass with a surrounding membrane that develops in or around the brain. This condition can be due to a complication of an infection elsewhere in the body, such as meningitis, sinusitis, or otitis media. It can also develop following trauma to the head or after surgery. Symptoms of a brain abscess include fever, headache, vomiting, and changes in mental status. If left untreated, a brain abscess can lead to seizures, coma, and death.
