Overview
If left untreated, a brain abscess can be fatal. Common complications include abscess rupture, hydrocephalus, and brain herniation. With treatment, the mortality rate decreases to about 10% of the population.
Natural History
If left untreated, a brain abscess is almost always fatal. If there is an abscess rupture into the ventricular system, ventriculitis can result.[1] Early detection and treatment is preferential. After surgery, some patients can experience long-term neurological problems.[2]
Complications
Common complications include:[1]
- Abscess rupture
- Hydrocephalus
- Brain herniation
Prognosis
With treatment, the mortality rate is about 10% to 30%. While the mortality rate was 40% in 1960, it has dropped down to 15% within the past decade alone. About 70% of patients with brain abscesses have a good outcome, rarely with minimal neurological sequelae.[1]
