Pneumocephalus in Otogenic Meningitis due to Streptococcus Agalactiae: a case report

Abstract

Pneumocephalus is defined as the presence of air in the intracranial cavity. This condition has multiple etiologies described such as traumatic or iatrogenic origins. Rarely, pneumocephalus has been reported in otogenic meningitis. Head computer tomography represents the gold standard imaging to visualize the quantity and localization of air. The work-up has to be completed by a lumbar puncture in suspected underlying infection. The treatment depends on the identified cause. We report the case of a 77-year-old man diagnosed with a pneumocephalus associated with otogenic meningitis.
