====== Intracranial epidural abscess epidemiology ======

Epidural abscesses are rare overall but together with subdural empyema account for around 20-33% of all intracranial infections. They can present in any age group and have no real gender predilection.

It is the third most common localized [[intracranial infection]], after [[brain abscess]] and [[subdural empyema]]

It is far less common than [[spinal epidural abscess]]. In the past, most cases of intracranial epidural abscesses were associated with [[sinusitis]], [[otitis]], or [[mastoiditis]]. Today, many cases arise as a complication of neurosurgical procedures
