Dural venous sinus stenting technique for idiopathic intracranial hypertension in patients with tortuous venous anatomy.

Venous sinus stenting (VSS) for medically refractory idiopathic intracranial hypertension (IIH) is emerging as a safe and effective alternative to shunting. However, stent navigation past the jugular bulb with commonly used carotid stenting systems via femoral access in cases with tortuous venous anatomy can present a challenge, leading to procedural failure. We present a technical refinement using a cervical access and peripheral vascular stent with a more stable 0.

Covered stent delivery in tortuous internal carotid artery for treatment of direct carotid cavernous fistula.

Direct carotid cavernous fistulas (dCCF) are high-flow shunts between the internal carotid artery (ICA) and cavernous sinus and are commonly caused by traumatic injuries. Endovascular intervention using detachable coils, with or without stenting, is often the treatment of choice; however, migration or compaction of the coils can occur due to high-flow nature of dCCFs. Alternatively, deployment of a covered stent in ICA can be considered for treatment of dCCFs.

Late Onset Symptomatic Enlargement of Treated Spinal Intradural Neurocysticercosis Cyst.

Cyst enlargement with progressive symptoms in spinal intradural Neurocysticercosis (NCC) is an uncommon finding after effective treatment of NCC. Neither imaging nor clinical presentation is sufficient to differentiate a sterile arachnoid cyst from recurrence of NCC. We present a case of symptomatic spinal intradural cyst enlargement 16 years after successful treatment of intracranial and spinal NCC with anti-helminthics.

Microsurgical and endoscopic anatomy of the extended retrosigmoid inframeatal infratemporal approach.

Background: Different and often complex routes are available to deal with jugular foramen tumors with extracranial extension.

Objective: To describe a novel extension of the retrosigmoid approach useful to expose the extracranial area abutting the posterior fossa skull base.

Methods: A navigation-guided, endoscope-assisted retrosigmoid inframeatal approach was performed on 6 cadaveric heads in the semisitting position, displaying an area from the internal acoustic meatus to the lower cranial nerves and exposing the intrapetrous internal carotid artery.

Anatomical variations and neurosurgical significance of Liliequist's membrane.

Introduction: Liliequist's membrane is an arachnoid membrane that forms a barrier within the basilar cisternal complex. This structure is an important landmark in approaches to the sellar and parasellar regions. The importance of this membrane was largely recognized after the advance of neuroendoscopic techniques.

Primary diffuse large B cell lymphoma of the cranial vault.

Primary non-Hodgkin's lymphoma of the cranial vault is extremely rare. This case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. Initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull.
