Overview
MRI
In patients with spinal epidural hematoma findings on MRI suggestive of spinal epidural hematoma include:[1][2]
Imaging findings in ASEH were the following: (a) a variable signal intensity (on T1-weighted images, 10 showed isointensity to cord and 7 were slightly hyperintense; T2-weighted images showed hyperintensity with areas of hypointensity); (b) capping of epidural fat; (c) direct continuity with the adjacent osseous structures; (d) compression of epidural fat, subarachnoid sac, and spinal cord; (e) usually posterolateral location in the spinal canal.
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]
