Subdural empyema (SDE) is collection of pus in the potential space between the dura
and arachnoid layers of the meninges. Leading causes of SDE are sinonasal and otomastoid
infections. Commonly affecting patients in the second and third decades, SDE could
have a fulminant course with immediate complications and delayed morbidities including
hydrocephalus, focal deficits, and epilepsy.
Key-words:
