Overview

Epidural abscess may be classified according to the location of the infection into 2 groups: intracranial and spinal.^[1] Additionally, spinal epidural abscess can be further classified based on the duration of symptoms into either acute or chronic.

Classification

Epidural abscess may be classified according to the location of the infection into 2 groups: intracranial and spinal.^[1]

Intracranial Epidural Abscess

The abscess is limited on the inner side by the cranial dura mater and on the outer side by the cranial bone.^[2]

Spinal Epidural Abscess

The abscess is limited on the inner side by the spinal dura mater and on the outer side, by the spinal canal.^[3] Spinal epidural abscess can be further classified based on the duration of symptoms into either acute or chronic.

Acute

Fever
Systemic toxicity
Peripheral leukocytosis
Usually posterior to spinal cord

Chronic

Fever absent
No elevated inflammation markers
Usually anterior to spinal cord
