Acute spinal subdural hematoma following lumbar puncture.

A case of acute spinal subdural hematoma following lumbar puncture in a patient with a normal coagulation profile is reported. Lumbar myelography may be unsuccessful. Other methods of myelography (via cisternal or lateral cervical puncture) to corroborate a block may be made or a laminectomy at the proper clinical level without further studies may be indicated.
