Learning objectives: To describe imaging anatomy of spinal epidural space To know the pathology of epidural space, classified in extrinsic and intrinsic lesions. To determine the causes: traumatic, degenerative, infective, neoplastic and others
Background: Definition: The spinal epidural space is located between the dura and the ligamentum flava and periosteum of the vertebral bodies, pedicles and laminae. (1) Extends from foramen magnum to posterior sacroccocygeal ligament. (2) Boundaries: Superiorly: Fusion of the spinal and p[...]
Findings and procedure details: INTRINSIC PATHOLOGY. (Fig.1) 1. DEVELOPMENTAL a. Vascular Malformation: on T2W hyperintense cord and intradural flow voids on cord surface. (Fig.2) 2. TRAUMATIC a. Hemorrhage : postrauma, post[...]
Conclusion: After an appropiate clinical assesment imaging is fundamental in the differential diagnosis of epidural processes. The use of the different MRI sequences will help as in the assesment of the multiple contents of the epidural space.
