Epidural Abscess: Sagittal MRIs of the Thoracic Spine; (Left) T1-weighted; (Middle) T1-weighted with gadolinium; (Right) T2-weighted. Note the lesion which is bright on T2-weighted images and enhances with gadolinium (middle image compared to the left). The lesion is clearly extra-axial and compresses the spinal cord. Emergency surgery demonstrated an epidural abscess with gram positive cocci.

Epidural abscesses most often occur from spread through the blood system to the vertebral body, directly to the epidural space, or both. Patients most often present subacutely over days with fever and spine pain, often followed by radicular symptoms and then frank spinal cord compromise.
