Overview
MRI is the preferred imaging study for diagnosis of spinal epidural hematoma. In patients with spinal epidural hematoma findings on MRI suggestive of spinal epidural hematoma include: A variable signal intensity( Isointensity to cord in T1-weighted images and Hyperintensity with areas of hypointensity in T2-weighted images), capping of epidural fat, direct continuity with the adjacent osseous structures and compression of epidural fat, subarachnoid sac, and spinal cord. MRI is sensitive for diagnosis of intracranial epidural hematoma but it is rarely used for diagnosis of it because of its limited availability and because more time is needed to prepare the patients for MRI.
MRI
- In patients with spinal epidural hematoma findings on MRI suggestive of spinal epidural hematoma include:[1][2]
- A variable signal intensity:
- Isointensity to cord in T1-weighted images
- Hyperintensity with areas of hypointensity in T2-weighted images
- Capping of epidural fat
- Direct continuity with the adjacent osseous structures
- Compression of epidural fat, subarachnoid sac, and spinal cord
- A variable signal intensity:
- MRI is sensitive for diagnosis of intracranial epidural hematoma but it is rarely used for diagnosis of it because of its limited availability and because more time is needed to prepare the patients for MRI.[3]
