特発性低髄液圧症候群：病態と診断・治療

抄録

Spontaneous intracranial hypotension (SIH) has become a well-recognized syndrome. However, diagnosis of SIH is still challenging. The problem with SIH is that the precise mechanism of cerebrospinal fluid (CSF) leakage remains largely unknown and there is no only definite criterion in the diagnostic imaging.

In this report, the author reviews on the pathophysiology of CSF leakage, clinical symptoms, findings of imaging studies, diagnostic criteria, and management of SIH.

The author mentions current controversy about the diagnostic criteria for patients managed as a posttraumatic CSF hypovolemia in Japan, and proposes the most adequate diagnostic criteria for CSF leaks and SIH.
