      Dural Venous Sinus Stenosis: Why Distinguishing Intrinsic-versus-Extrinsic Stenosis Matters  
    	S.H. Sundararajan, A.D. Ramos, V. Kishore, M. Michael, R. Doustaly, F. DeRusso and A. Patsalides
  
    	American Journal of Neuroradiology February 2021, 42 (2) 288-296; DOI: https://doi.org/10.3174/ajnr.A6890 
  
    	Most patients in this study with idiopathic intracranial hypertension had extrinsic stenosis, and most patients with pulsatile tinnitus had intrinsic stenosis. Awareness and reporting of these subtypes may reduce the under-recognition of potential contributory stenoses in a given patient's idiopathic intracranial hypertension or pulsatile tinnitus.

    	The aneurysm neck located on the outer convexity is a new, incomplete occlusion predictor, joining older age, fusiform aneurysms, and aneurysms with the branching artery from the dome. No permanent neurologic deficits or rupture were observed in the follow-up, even with incomplete occlusion.

      Characteristics of Large-Vessel Occlusion Associated with COVID-19 and Ischemic Stroke

    	American Journal of Neuroradiology December 2020, 41 (12) 2263-2268; DOI: https://doi.org/10.3174/ajnr.A6799 
  
    	Consecutive ischemic stroke and TIA admissions (COVID and non-COVID) to the authors' hospital during a 10-week period from March 1 to May 10, 2020 were collected and compared with data from the same time period in 2019. Among 20 patients with COVID-19 and acute ischemic stroke, 15 (75%) had large-vessel occlusion. These patients were young (mean age, 46.5 years), male (93%), without major burden of traditional cardiovascular risk factors, and had a severe stroke presentation. Large vessel occlusions were observed in multiple vessels (40%), uncommonly affected vessels, and atypical locations with a large thrombus burden.
