Overview The majority of cases of brain abscess are due to infections with either bacteria or fungi. Common causes of brain abscess include Cryptococcus neoformans Staphylococcus aureus Toxoplasma gondii Viridans streptococci
Causes Brain abscesses commonly occur when bacteria or fungi infect part of the brain. The source of the infection, however, is often not found. The germs that cause a brain abscess usually reach the brain through the blood. Germs may also travel from a nearby infected area (such as an ear infection), can enter the body during an injury (from a gun or knife wound), or result from surgery. Though not as often, a heart infection can also be a cause of brain abscesses.[ 1] [ 2]
