The Analysis Of Spontaneous Intracranial Hypotension Syndrome In 17 Cases

Objective : To explore the clinical features, pathogenesis , cerebrospinalfluid(CSF) and imaging changes of spontaneous intracranial hypotensionsyndrome.Methods : 17 cases with spontaneous intracranial hypotension syndrome wereretrospectively analysed.Results : Their symptoms were all classical with headache in uprightposture,partly including nausea,vomiting, tinnitus , dizziness and neck stiffness. The pressure were all less than 70 mmH₂O by lumber puncture. CSF contained small amount of RBC and protein increased. MRI revealed subdural hygromas,subdural hematoma and diffused dural enhancement. Conclusions : It's very important to understand the clinical features, pathogenesis , cerebrospinal fluid(CSF) and imaging changes of spontaneous intracranial hypotension syndrome. We should on guard against the complication of subdural hematoma and identify it from subarachnoid hemorrhage.
