Patients with brain abscess generally appear healthy. Most findings are neuromuscular in nature.


==Physical Examination==
==Physical Examination==
The symptoms of brain abscess are caused by a combination of increased [[intracranial pressure]] due to a space-occupying lesion ([[headache]], [[vomiting]], [[confusion]], [[coma]]), [[infection]] ([[fever]], [[fatigue]] etc.) and focal neurologic brain tissue damage ([[hemiparesis]], [[aphasia]] etc.). The symptoms and findings depend largely on the specific location of the [[abscess]] in the brain. An [[abscess]] in the [[cerebellum]], for instance, may cause additional complaints as a result of [[brain stem]] compression and [[hydrocephalus]]. [[Neurological examination]] may reveal a stiff neck in occasional cases (erroneously suggesting meningitis). The famous triad of [[fever]], headache and focal neurologic findings are highly suggestive of [[brain abscess]] but are observed only in approximately 40-50% of patients.<ref> Brain Abscess.
