Intracranial Epidural Abscess and Subdural Empyema
Symptoms and Signs
Fever, headache, lethargy, focal neurologic deficits (often indicating subdural empyema when rapidly developing deficits suggest widespread involvement of one cerebral hemisphere), and seizures usually evolve over several days. Patients with intracranial epidural abscess may also develop a subperiosteal abscess and osteomyelitis of the frontal bone (Pott puffy tumor), and patients with subdural empyema often develop meningeal signs. In epidural abscess and subdural empyema, vomiting is common. Many patients may develop Papilledema . Without treatment, coma and death occur rapidly, particularly in subdural empyema.
