Brain MRI features of postdural puncture headache
Authors' conclusion
The radiological characteristics of IHS and PDPH are most likely the result of compensatory mechanisms in response to decreased cerebrospinal fluid pressure. The acute nature of PDPH probably causes its radiological MRI characteristics to differ from those of IHS, given that no brain sagging could be demonstrated.
Study context

- Outcome
- Radiological findings specific to PDPH on brain MRI
- Follow-up
- Within 48-72 hours after the onset of their orthostatic headache
