Cervical epidural spinal infection: MR imaging characteristics.

The results of our study show that cervical epidural spinal infection is a more aggressive disease than previously recognized. MR findings are characterized by multilevel involvement, an anterior location, and frequent abscess formation. MR evidence of isolated involvement of the epidural space, without underlying osseous abnormality, is rare. There is a predilection for infection to affect the lower cervical segments. We observed a strong association between cervical epidural spinal infection and spinal cord compromise, which makes prompt diagnosis and treatment mandatory.
