SECONDARY HEADACHES: SPONTANEOUS INTRACRANIAL HYPOTENSION (LOW CSF PRESSURE HEADACHES)

Purpose of Review: More patients with spontaneous intracranial hypotension are now being diagnosed, and it is realized that most cases result from spontaneous cerebrospinal fluid leaks. A broader clinical and imaging spectrum of the disorder is recognized. This paper reviews new insights into the variability of clinical manifestations, imaging features, etiological factors, anatomy of leaks, and implications of these in patient management.
