Abstract

Objective To explore the Magnetic resonance imaging(MRI) findings of Spontaneous intracranial hypotension syndrom(SIHS).Materials and Methods The clinical and imaging data of 8 patients with SIHS were retrosepectively analyzed.Results MRI findings included dural thickening and subdural fluid collection in 8 cases,cerebral veins dilated in 7 cases,brain descensus in 2 cases,and enlargement of pituitary gland in 1 cases.Contrast T1-weighted MR scan showed diffused endocranium thickening and enhancement in 6 cases.On spinal cord MRI,subarachnoid space showed narrow and epidural fluid collection in 2 cases.Eight patients had lower CSF pressure(60 mm H2O).Conclu-sion MRI can reveal the characteristic findings of SIHS,which contribute to the clinical diagnosis.
