Combined fourth and sixth cranial nerve palsy after lumbar puncture: a rare complication. A case report.

Palsies of cranial nerves are well-known complications after lumbar puncture. Sixth nerve palsies are the most common. They normally occur 4 to 14 days after the lumbar puncture and spontaneously recover in a few weeks or months. The occurrence of a fourth nerve palsy following lumbar puncture however is extremely rare. We report on a patient who developed a combined contralateral fourth and sixth nerve palsy after lumbar puncture (Syndrome of Intracranial Hypotension), requiring surgical correction for secondary diplopia.
