[Abducens nerve palsy in spontaneous intracranial hypotension].
Described by Schaltenbrand (1940), spontaneous intracranial hypotension is an unusual syndrome, sometimes revealed by an abducens nerve palsy motivating the patient to consult emergency ophthalmology services. The Authors report the case of a 50-Year-old Turkish woman who presented with diplopia due to a left abducens nerve palsy. These symptoms were associated with headache and nausea. Brain magnetic resonance imaging demonstrated diffuse pachymeningeal enhancement with gadolinium. A lumbar puncture showed low spinal fluid pressure (6 cm H2O), leading to the diagnosis of palsy by spontaneous intracranial hypotension. First, a classic treatment was prescribed with no result: increased water intake, corticoid therapy, and rest. Then a blood patch consisting of an injection of autologous blood by lumbar puncture between the third and fourth lumbar vertebrae to plug the spontaneous leak of spinal fluid, with success. A review of the literature provides information on the physiopathological mechanism, the clinical and imaging symptoms, and the treatment.
