[Chronic subdural hematoma secondary to an accidental dural puncture during lumbar epidural anesthesia].

We report the case of a 54-year-old woman with cephalea of five months duration caused by a chronic subdural hematoma that appeared after epidural anesthesia and accidental dural puncture for bilateral saphenectomy. Computed tomography of the brain revealed an intracranial hematoma. After surgical evacuation, the patient's headaches resolved and she recovered fully. The appearance of cephalea after dural puncture is a relatively frequent complication of spinal anesthesia, but its persistence over time, as well as changes in its initial characteristics, should lead to a suspicion of life-threatening subdural hematoma.
