Subdural Empyema as a Rare Complication Caused by Neisseria meningitidis B

Subdural empyema (SDE) is an intracranial collection of purulent material located between the dura and the arachnoid mater. It is a serious central nervous system infection which can cause neurological sequelae and high mortality. We report one of the rare cases of SDE secondary to Neisseria meningitidis to underline the interest of evoking this diagnosis especially in patients not responding to standard antimicrobial therapy.
