[Abstract] Objective: To investigate the clinical presentation and MRI characteristics of spontaneous intracranial hypotension (SIH) syndrome.Materials and Methods: Retrospective analysis of clinical presentation and MR imaging of 22 SIH patients, to summarize the characteristics of clinical presentation and MRI of (SIH).Results: Typical postural headache and the low CSF pressure (less than 60 mm H2O) ware found in the all patients. In the 22 patients, 10 cervical rigidity and 8 Hearing Disorders ware found. On MRI, all patients showed pachymeningeal diffuse enhancement, other findings included sagging brain (20), diminution of cerebral ventricles (10), enlargement of venous sinus (7).Conclusions: Postural headache and the low CSF pressure are the important clinical characteristics of SIH, diffuse enhancement of cerebral dura mater and sagging brain are the important MRI characteristics of SIH, enhanced MR was the important method in diagnosis of SIH.
