Where is the epidural hematoma located in the neuraxial space? What signs/symptoms correlate with which hematoma location?

Isolated back pain usually signals a hematoma in the posterior epidural space which is impinging on nerve fibers to the posterior structures. Back pain along with lower extremity pain and/or sensory or motor deficit heralds a hematoma in the posterolateral epidural space which is also impinging on the nerve roots. If the hematoma blocks the entire spinal canal, it will cause cauda equina syndrome with urinary or fecal incontinence and weakness of lower extremities which is associated with complete obliteration of the thecal sac.
