Spinal subdural hematoma.

: The authors report a case of spinal subdural hematoma in a 51-year-old man who experienced a sudden onset of back pain accompanied by vomiting and headache without paralysis or paraparesis. CT Scan, myelography and MRI revealed a subdural hematoma at the levels of 6th, 7th and 8th thoracic vertebrales. Laminectomy allowed the removal of an encapsulated cyst formation filled with xanthochromic fluid and some blood clots. The follow-up was uneventful.
