Case Reports[Spontaneous intracranial hypotension: a rare cause of chronic headache].
Spontaneous intracranial hypotension is a rare cause of chronic postural headache. We report the case of a 58-year-old woman with a 1.5 year history of chronic headache in upright position, nausea and vomiting. Neurological examination was normal. ⋯ The headache was alleviated under theophylline therapy. Spontaneous intracranial hypotension should be considered in the differential diagnosis of chronic postural headache. MRI revealing meningeal enhancement and low opening pressure in lumbar puncture are important findings for the diagnosis of spontaneous intracranial hypotension.
