Note: Symptoms may develop gradually, over a period of 2 weeks, or they may develop suddenly. Once symptoms occur, they progressively worsen.

Signs and tests:

A neurologic examination will usually reveal increased intracranial pressure and problems with brain function causing confusion or other problems. The problems will relate to the area of the brain where the abscess is located. The physician will look for the possible source of the infection.

CBC may indicate infection or inflammation.
Blood cultures should be done but usually do not help identify the infecting organism.
Chest X-ray will reveal lung infections (one of the more common sources of infection).
EEG may be abnormal if seizures or focal neurologic deficits are present.
Cranial CT scan or MRI of head shows the abscess and its exact location.
