high risk brain abscess
Risk is increased in immunocompromised patient
Prevent brain abscess
treating otitis media, mastoiditis, sinusitis, dental infections, and systemic infections promptl
signs brain abscess
headache that is usually worse in the morning, fever, vomiting, neurologic deficits, and signs and symptoms of increased ICP
diagnosis brain abscess
