title: [Idiopathic hypotension of the cerebrospinal fluid].
abstract: A case of spontaneous hypotension of the cerebrospinal fluid (CSF) is reported. A 32 years-old woman was complaining of intense orthostatic headaches. CT scan showed slit ventricles and the spinal tap showed a pressure of the CSF too low to be measured. A sample of clear CSF could only be obtained by aspiration. The patient's status improved without drugs by simply staying in bed for one week. Few similar cases have been reported. The mechanisms of this disorder still remains unknown.
