Abstract: Objective To study the clinical and imaging characteristics as well as cerebrospinal fluid chan-gea(CSF) of spontaneous intracranial hypotensian syndrome (SIHS).Methods The clinical characteristics, CSF and imaging data of 13 patients diagnosed as SIHS were retrospectively analyzed.Results All the 13 patients had orthostatic headache accompaning one or more numerous symptoms including nausea, vomiting, dizziness, diplopia and neck stiffness.All the patients had low CSF pressure,which was below 60 mm H2O and high CSF protein was in 5 patients, 8 had increased white cell counts and 9 had increased red cells counts;CT was performed in all patients.On CT scan the subdural effusion or small ventricles were compressed in 4 patients.MRI typically revealed diffused pachymeningeal enhancement in 2 patients;All the patients experienced relief of symptoms through conventional treatment.Conclusion Orthostatic headache is the most typical symptom in spontaneous intracranial hypotension syndrome and diffused pachymeuingeal enhancement is the most common imaging manifestation, and CSF hypovol-emia is the basis of pathophysiology of spontaneous intracranial hypotension syndrome.
