SPONTANEOUS INTRACRANIAL HYPOTENSION - ON E CASE

We report a 49-year-old woman with spontaneous intra-cranial hypotensi on. This characteristic syndrome associates postural headache and a lo w cerebro-spinal fluid pressure. It was confirmed by lumbar puncture a nd magnetic resonance imagery. We describe the clinical and the cerebr o-spinal fluid features, the radiological appearances, and the clinica l and radiological course. The interests of this diagnosis are, first, its spontaneous benign course and, second, to avoid unnecessary invas ive investigations.
