Spinal Subdural or Epidural Hematoma
Key Points
Suspect spinal subdural or epidural hematoma in patients with local or radicular back pain and percussion tenderness or sudden, unexplained lower-extremity paresis, particularly if a possible cause (eg, trauma, bleeding diathesis) is present. Diagnose using MRI or, if MRI is not immediately available, CT myelography. Immediately drain the hematoma surgically.
