Spinal extradural arachnoid cyst surgery. Profound redundant arachnoid, mercifully small dural defect. Mysterious that some pts have orthostatic HA and others compressive myelopathy.
Dilemma addressed by @MarkMamloukMD @Niklas_Luetzen recently PMID 40441881
Contemplated this case while traveling to inaugural @issclsociety mtg. Pt in 20s w numb/weak BLE with bend/twist. Never HA.
Spinal extradural arachnoid cyst
Analagous to a Type II CSF leak
Straightforward OR... Resect extradural arachnoid, close small dorsal dural defect

Thank you to all the attendees who joined the inaugural @issclsociety meeting. The world experts on #spinalCSFleak!
Curious about experiences stenting IIH post-CVST?
Despite diffuse stenosis and irregular walls, even crossing jugular bulb, I've had great results in pts w recalcitrant papilledema.
Route92 half-cath w Tenzing delivery assist is transformational technology for sinus stenting.
Which of these aneurysms do you think ruptured? Based on imaging? Based on intra-op findings?
I'm still not certain. I initially deferred the basilar, ultimately took hybrid approach to cure all

IT cardene works best when started before any sign of ischemia in aneurysmal SAH @URNeurosurgery @URNeuroscience
🚨 New study in Clinical Neurology and Neurosurgery on aneurysmal subarachnoid hemorrhage (aSAH) management 🩸 🧠
Anticipatory initiation of Intrathecal Nicardipine (ITN)—given before clinical or imaging evidence of delayed cerebral ischemia (DCI)—significantly reduces DCI parenchymal infarcts compared to controls (31.3% vs 55.2%).
Key findings:
📉 Starting ITN prior to intra-arterial (IA) spasmolytics significantly lowers the need for serial IA treatments for recalcitrant vasospasm from 71.4% down to 23.1%.
🛡️ It is a safe intervention with no increased risk of EVD-related complications or meningitis.
⚠️ Timing is everything, because reactionary ITN given after DCI onset did not reduce the rate of additional infarcts or the need for serial IA treatments.
Question: Does this article change your practice?

Kicking off day 3 of the 2026 #cerebralvenous & #CSF Disorders Summit with @mtbendermd and Emanuele Orru’, MD 📝
Skills lab today @URNeurosurgery simulating type 2 and 3 CSF leak repair. Seeing more and more of these cases. Great to practice and teach technique. Appreciate educational grant support from @BioventusGlobal for bone scalpel laminoplasty. @spinalCSFleak
Such a treat to visit and share my experience treating patients with spontaneous intracranial hypotension. Clever residents and inspiring faculty! @spinalCSFleak @URNeurosurgery
We are honored to welcome Matthew T. Bender, M.D., from @URNeurosurgery, as our Invited Visiting Professor! Join us as we host Dr. Bender for an insightful session sharing his expertise in neurosurgery and patient care. #VisitingProfessor #WakeForestNeurosurg
What is the inciting insult in #IIH? We’ve argued it’s glymphedema and interstitial fluid accumulation. Excited to see this come out in @HeadacheJournal
@URNeuroscience @URNeurosurgery
🧠 New narrative review: A proposed disease model for #IIH suggests altered brain fluid regulation, linked to obesity, may drive a cycle of fluid buildup, venous compression, & ⬆️intracranial pressure.

After two years and thousands of manuscripts, I’ve learned that the real work of an editor isn’t gatekeeping — it’s partnership.

Congrats to @AaronAnandaraj1 one of our most productive @penn undergraduates in the #NeuroVERT lab, now a med student up in Rochester.
Look forward to following your work with @mtbendermd and crew – at Philadelphia, PA

Thrilled to show our findings implicating the glymphatic system in futile recanalization after thrombectomy in LVO #stroke. Is the glymphatic system a potential therapeutic target? @mtbendermd
