The Analysis of Spontaneous Intracranial Hypotension Syndrome in 17 Cases
|Keywords||Primary low intracranial pressure Headache Magnetic resonance|
[ Objective] To investigate the clinical features of primary intracranial hypotension syndrome , pathogenesis , cerebrospinal fluid ( CSF ) and imaging changes . [Methods ] Retrospective analysis of clinical data of 17 patients with primary low intracranial pressure syndrome . [Results ] All patients had orthostatic headache, in some cases accompanied by nausea, vomiting, ringing in the ears , dizziness, stiff neck ; lumbar puncture pressures were lower than 70mmH 2 < / sub > O , CSF may contain a few red blood cells , protein content increased ; brain magnetic resonance imaging (MRI) shows subdural effusion, subdural hematoma and diffuse dural enhancement . [Conclusion] understanding of the primary low intracranial pressure syndrome clinical features , pathogenesis , CSF and MRI performance is critical , the disease should be alert to the occurrence of a subdural hematoma , and note with subarachnoid hemorrhage identification.
