Spontaneous Spinal Epidural Hematoma: Report of Two Operative Cases

Spontaneous spinal epidural hematoma is a rare disease. Typically, a healthy man engaging in usual activity of daily life develops back or neck pain suddenly and most victims are unable to walk within 6 hours. We treated two cases of spontaneous spinal epidural hematoma surgically. On case developed hematoma in the thoracolumbar junction in a adult man, and the cause of hematoma could not be confirmed with surgery. Another case developed hematoma in the midthoracic area in a boy, and the source of bleeding was confirmed as arteriovenous malformation in spinal epidural fat tissue. Related literatures were reviewed.
