"While we found a statistically significant higher renal contrast excretion in patients with SIH compared with patients without SIH during early-phase CTM, no useful threshold value could be established that could reliably distinguish these groups with both high sensitivity and high specificity."

📄New paper on ICP monitoring in pts with orthostatic HA and negative imaging found that most common identifiable pressure issue was high pressure (!) “3 patients had low ICP (8%) and 6 patients had high ICP (16%). The remaining [had neither] (76%). 🤔 pubmed.ncbi.nlm.nih.gov/39905291/

So what exactly makes a headache orthostatic anyway? 📄 New paper alert 📄 journals.sagepub.com/doi/full/10....

Most EBPs in the community are performed without imaging guidance. Case report of how an intact plica dorsalis mediana prevented bilateral spread of blood, necessitating a second EBP under imaging. Consider when EBP for PDPH “fails.” scholar.google.com/scholar_url?...

📄 New Paper Alert! 📄 “Flow Void Sign”: Flow Artifact on T2-Weighted MRI Can Be an Indicator of Dural Defect Location in Ventral Type 1 Spinal CSF Leaks Congrats to @neuroradlal.bsky.social, @dgleao.bsky.social , David Butteriss, @brainscandan.bsky.social - super useful - I'm a believer!!

Headache that worsens upon standing may prompt suspicion for CSF leak. But there is a normal sharp spike in CSF pressure immediately upon standing. In some patients with IIH or RIH, this can paradoxically cause HA upon standing, tho usually transient. Fig: PMID 34715658

Fascinating series of articles on CTD in Neurology in #FrontiersinNeurology including #CSFleak and orthostatic HA. Great discussion and hypotheses- but surprising how little primary data underpins our current understanding. #knownunknowns www.frontiersin.org/research-top...
