Hydrocephalus and Intracranial Hypertension by an Odontogenic Brain Abscess

Rogério P Amorim et al. Cureus. .

Abstract

Brain abscesses are rare and severe infections with high mortality, corresponding to neurosurgical emergencies. 12% of all abscesses are caused by odontogenic etiologies, either an infectious process or a dental procedure. This paper describes a case of a patient who underwent tooth extraction, presenting days later with hydrocephalus and intracranial hypertension due to a brain abscess, whose isolated pathogen is the same identified in the oral cavity.

Keywords: adult hydrocephalus; brain abscess; intracranial hypo-hypertension; streptococcus intermedius bacteremia; tooth extraction.
