1. Spinal subdural and epidural hematomas are rare neurologic emergencies which can result from several different etiologies and have devastating neurologic sequelae. 2. Common etiologies for both subdural and epidural spinal hemorrhage include trauma, lumbar puncture, spinal surgery and spinal anesthesia.  

Anatomy: • Pia, Arachnoid, Dura • Epidural & subdural spaces • Epidural venous plexus and fat MRI: • Aging of blood products- hyperacute, acute, early and late subacute, chronic • Use of gradient echo with hyperacute hemorrhage Spinal Subdural Hemorrhage: • Pathophysiology • Presentation • Etiologies with MR example of each: trauma, lumbar puncture, spinal anesthesia, spine surgery, bleeding diathesis, anticoagulation therapy, vascular malformations, non-accidental trauma, posterior fossa decompressive surgeries • MR imaging techniques and features • MR pitfalls • Complications Spinal Epidural Hemorrhage: • Pathophysiology • Etiologies with MR example of each: spontaneous, trauma, spinal anesthesia, spine or brain surgery • Presentation • MR imaging techniques and features • MR pitfalls • Complications
