Abstract：Objective To study the imaging manifestation of spontaneous intracranial hypotension syndrome. Methods The clinical data and imaging findings of 15 cases of spontaneous intracranial hypotension syndrome confirmed by clinic were retrospectively analyzed with literature review. 15 cases had the brain routine CT and MRI scan, in which there were 15 cases with MRI brain contrast-enhanced scan, 2 cases with spinal MRI scan. Results There was no obvious abnormal in 8 cases of head CT scan in 15 cases. Subdural effusion was found in 4 cases, small quantities of subdural hematoma in 2 cases, and dural thickening in 1 case. Head MRI all showed signs of brain sagging, pituitary fullness in 3 cases, pituitary enlargement in 1 case, subdural effusion in 4 cases, all of the 15 cases presented with brain contrast-enhanced. MRI scan appeared linear no-nodular and diffusely meningeal enhancement; In 2 cases for spinal MRI scan, there were 2 cases with extradural fluid conllection, 2 cases with linear spinal dural enhancement. Conclusion MRI is specific for the diagnosis of spontaneous intracranial hypotension syndrome, CT is sensitivity difference for the spontaneous intracranial hypotension syndrome.
