Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
Ear infections, on the other hand, can lead to brain complications because the inflammation from a viral infection (like RSV, adenovirus, rhinovirus or influenza) causes swelling that prevents the ...
The close proximity of the sinuses to the brain makes brain infections one of the most dangerous complication of acute bacterial sinusitis, especially when the frontal and sphenoid sinuses are involved. These infections can result from invasion of anaerobic bacteria through the bones or blood vessels.
Symptoms include common problems such as head aches, fevers, and nausea, but the more telling signs that a bacterial infection may have reached the brain are sensitivity to light, seizures, having limited range in neck movement, and easy bruising all over the body.

The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
The symptoms confused hospital staff, and a CT pointed to a possible tumor. What the CT actually showed was a lesion on her brain and upon opening her skull a surgeon discovered the amoeba infection.
