What the literature leaves open

  • Although the adult-only sensitivity description showed findings similar to those of the full cohort, the small number of pediatric patients precluded meaningful age-stratified comparisons, and residual age-related heterogeneity remains an important limitation. Consequently, the specificity of the observed HR-VWI patterns and their ability to distinguish CNS vasculitis from relevant mimics could not be assessed.

    High-Resolution 3T Intracranial Vessel Wall MRI in Patients Evaluated for Suspected Inflammatory Intracranial Vasculopathy: Morphologic and Follow-Up Findings from a Retrospective Case Series · 2026 · DOI

  • Obstrictive sleep apnea was not systematically assessed in our cohort; therefore, its potential confounding effect on nocturnal blood pressure abnormalities could not be evaluated.

    Increased prevalence of ambulatory and isolated nocturnal hypertension in children with idiopathic intracranial hypertension: a case–control study · 2026 · DOI

  • Lastly, although baseline CSF NLRP3 levels demonstrate potential for prognostic stratification, their complete biological significance and the underlying regulatory mechanisms warrant further exploration.

  • Further study into the efficacy of WEB devices in the treatment of aneurysms of the jugular bulb would be beneficial, as two of the three WEB devices used in our cohort were removed due to suboptimal placement.

    Embolization of jugular bulb diverticula in the management of pulsatile tinnitus · 2026 · DOI

  • This systematic review highlights the heterogeneity of the available evidence, with most published studies focusing on cerebral venous sinus thrombosis rather than postoperative venous sinus stenosis, and demonstrates the limited evidence supporting endovascular management for the complications mentioned above.

    Postoperative venous sinus stenosis after retrosigmoid craniotomy: systematic review and illustrative case · 2026 · DOI

  • Third, many studies primarily focused on postoperative cerebral venous sinus thrombosis, whereas isolated postoperative venous sinus stenosis was infrequently reported, resulting in limited evidence specifically addressing the clinical scenario presented in our illustrative case.

  • Age-related ocular rigidity of the lamina cribrosa and sclera, implicated in the pathogenesis of glaucoma, may in theory affect the susceptibility of the ONH to NAION, though this remains to be demonstrated.

    Optic disc drusen prevalence and visual outcome in a cohort of patients with non-arteritic anterior ischemic optic neuropathy · 2026 · DOI

  • The internal cerebral veins appeared fully recanalized (b), while partial recanalization with residual mural thrombi persist in the straight sinus and sinus confluence (c) hemorrhagic complications, though evidence in pediatric patients remains sparse and only few reports on deep venous involvement in pediatric patients do exist.

    Procedural Framework for Combined Mechanical Thrombectomy and Continuous rtPA Thrombolysis in the Recanalization of Deep Cerebral Venous Thrombosis in a Pediatric Patient · 2026 · DOI

  • A key limitation of this review is the deliberate focus on a narrowly defined IIH cohort with sight-threatening disease, which necessitated exclusion of a substantial body of broader IIH intervention literature.

    Cerebrospinal fluid shunting and venous sinus stenting in sight-threatening idiopathic intracranial hypertension: a practical review of current evidence · 2026 · DOI

  • The observational nature of the data and limited sample size. The presence of concurrent traumatic brain injury (TBI) and other injuries that complicate treatment decisions. The need to minimize overinterpretation of potentially confounded associations.

    Management and Outcomes in Traumatic Cerebral Venous Sinus Thrombosis · 2026 · DOI

  • The validity of our prevalence estimates, subgroup comparisons and regression analysis is limited by the retrospective nature of our study, with varying imaging protocols and a proportion of patients missing visual follow-up.

    MRI features in atypical idiopathic intracranial hypertension · 2026 · DOI

  • The precise clinical significance of a persistent dehiscence remains uncertain, though our results suggest that post-operative temporal bone remodeling may serve as an imaging biomarker of a durable anatomical outcome. However, direct histopathological evidence is lacking.

    Temporal bone remodeling after venous stenting for pulsatile tinnitus: isolated dehiscence versus diverticulum · 2026 · DOI

  • This combination has rarely been reported and highlights the need to consider systemic embolic complications during intraocular surgery, even when intravascular air is not directly visualized on imaging.

    Case Report: Cerebral air embolism following fluid–air exchange during pars plana vitrectomy: a rare but severe complication · 2026 · DOI

  • This may suggest that sex-related risk factors become more influential after puberty and this needs to be examined further in future studies.

    Incidence of idiopathic intracranial hypertension (IIH) in adults and children: a 14-year population-based study · 2026 · DOI

  • Whether a causal relationship to an underlying genetic disorder exists in our patient remains uncertain.

    Non-restrictive cerebral venous dysgenesis in an 11-year-old girl: a case report · 2026 · DOI

  • Clinically, these findings suggest that anatomical imaging alone, showing absent straight sinus, is insufficient for risk stratification.

    Personalized Computational Fluid Dynamics Analysis of Cerebral Venous Hemodynamics in a Case of Deep Cerebral Vein Thrombosis · 2025 · DOI

  • This mutation is distinct from the well-established Leiden mutation and has not been previously reported.

    Association of the Coagulation Factor V c.3865T>G Mutation with Genetic and Regional Susceptibility to Cerebral Venous and Sinus Thrombosis in Xiangyang · 2025 · DOI

  • Whether or not the seemingly reduced number of large cortical veins is directly related to the abnormal appearance of the pial and small cortical veins remains unclear.

    Non-restrictive cerebral venous dysgenesis in an 11-year-old girl: a case report · 2026 · DOI

  • Finally, long-term angiographic outcomes were not systematically evaluated, which warrants further investigation.

    Safety and efficacy of endovascular treatment in symptomatic pediatric cerebral venous sinus thrombosis · 2026 · DOI

  • There is a lack of research on the use of integrative therapies in chronic neurological conditions. Conventional therapies often leave residual neurological deficits and functional impairments.

    Integrative Management of Chronic Cerebral Venous Sinus Thrombosis with Ayurveda and Physiotherapy: A Case Report · 2026 · DOI

  • Future studies should investigate the clinical implications of anatomical variations of the dural venous sinuses. Future studies should develop and validate a classification system for CS patterns. Future studies should examine the relationship between anatomical variations and venous pathologies.

    Morphological variations of the dural venous sinuses: a cadaveric study · 2026 · DOI

  • There is a lack of understanding of the anatomical variations of the dural venous sinuses. There is a need for a framework for understanding and classifying these variations.

    Morphological variations of the dural venous sinuses: a cadaveric study · 2026 · DOI

  • This finding suggests that the age-related decline in gland height does not account for the high rate of ES in older IIH patients and supports its utility as a diagnostic sign across all age groups.

    MRI features in atypical idiopathic intracranial hypertension · 2026 · DOI

  • Although limited by the small sample sizes, our data suggest that patients with more severe COVID-19 might have a worse long-term clinical outcome.
