Epidural hematoma after epidural catheterization is very rare but one of serious complications. Although true incidence and origin is unknown yet, coagulopathies and anticoagulant therapy are predominant risk factors. Other risk factors are NSAIDs treatment and ankylosing spondylitis. We experienced a case of epidural hematoma without any risk factors after epidural catheterization for postoperative pain control. We performed epidural catheterization before operation and postoperatively the patient received continuous epidural infusion for postoperative pain control. On the first operative day, the patient was noted to have developed complete paraplegia and hypoesthesia below L1 and anesthesia below L2 level. Immediately after noting we performed TL-spine MRI and epidural hematoma at T10 level was diagnosed and treated by decompressive laminectomy. But she has not fully recovered yet.
