Intracranial epidural abscess: a report of three cases

Intracranial epidural abscess is an uncommon but potentially life-threatening condition requiring prompt recognition and management. Most commonly it arises secondary to infection in the paranasal sinuses, mastoid air cells or the middle ear. It has also been described following craniotomy and trauma. This report describes three cases reported to our institution over a 15 month period, two associated with frontal sinusitis and one with no obvious predisposing factor.
