Comparing Outcomes of Patients With Idiopathic Subarachnoid Hemorrhage by Stratifying Perimesencephalic Bleeding Patterns
Background: To determine the clinical outcomes of perimesencephalic subarachnoid hemorrhages based on the computed tomography (CT) bleeding patterns. Methods: This retrospective cohort study included: (1) patients ( ≥18 years) admitted to a comprehensive stroke center (January 2015-May 2018), (2) with angiography-negative, nontraumatic subarachnoid hemorrhage in a perimesencephalic or diffuse bleeding pattern, and (3) had CT imaging performed in less than rqual to 72 hours of symptom onset. Patients were stra tified by location of bleeding on CT: Peri-1: focal prepontine hemorrhage; Peri-2: prepontine with suprasellar ci...

Letter to the Editor Regarding “Bioccipital Lobe Hypoperfusion and Anton's Syndrome Resolution with Intravenous Thrombolysis”
We have read with great interest the article by Rotkopf et al.1 The authors presented a rare case of Anton's syndrome confirmed by multiparametric computed tomography (CT) and completely resolved after the administration of recombinant tissue plasminogen activator (rtPA). We absolutely agree with the authors that multiparametric CT imaging may aid in quickly proving the underlying stroke in Anton's syndrome, especially helpful considering the discrepancy between the patient's perception and clinical examination results.

CT-based Higher Thrombus Density is associated with Secondary Embolism during Mechanical Thrombectomy: A Preliminary Observation
This study addresses a potential relationship between thrombus density on preinterventional computed tomography (CT) and the occurrence of SE. Methods: We reviewed anterior circulation AIS patients who underwent MT from July 2015 to January 2019 in our center. Thrombus density was measured in Hounsfield Units (HU) on 1-mm and 5-mm preinterventional nonenhanced CT (NECT).

Computed Tomography Perfusion Showing Cerebral Hypoperfusion in a Patient with Acute Cerebral Venous Sinus Thrombosis —A Case Report
We report the case of a patient with acute CVST, showing perfusion abnormalities on computed tomography perfusion with perfusion defect in the relevant hemisphere. The defect was found in a region adjacent to the occluded sinus and was not corresponding to an arterial territory. To the best of our knowledge this is the first ever report on CT perfusion abnormalities few hours after acute symptom onset in CVST.

White Matter Lesion Severity is Associated with Intraventricular Hemorrhage in Spontaneous Intracerebral Hemorrhage
Background: Intraventricular hemorrhage (IVH) and white matter lesion (WML) severity are associated with higher rates of death and disability in intracerebral hemorrhage (ICH). A prior report identified an increased risk of IVH with greater WML burden but did not control for location of ICH. We sought to determine whether a higher degree of WML is associated with a higher risk of IVH after controlling for ICH location. Methods: Utilizing the patient population from 2 large ICH studies; the Genetic and Environmental Risk Factors for Hemorrhagic Stroke (GERFHS III) Study and the Ethnic/Racial Variations of Intracerebral Hemo...

Intracranial Aneurysms After Intravenous Thrombolysis in Patient with Atrial Myxoma: A Case Study
We administered intravenous thrombolytic therapy to a 51-year-old female patient with a 101-min stroke onset. The patient was unconscious during the manifestation of symptoms. Computed tomography angiography examination of the intracranial artery at the time of admission suggested that the left middle cerebral artery was occluded. The patient regained consciousness after the intravenous thrombolytic treatment was administered. On an urgent cerebral angiography, it was revealed that the recanalization of the left middle cerebral artery was successful.

Ischemic Tolerance Evaluated by Computed Tomography Perfusion during Balloon Test Occlusion
In this study, we evaluated the utility of computed tomography (CT) perfusion during BTO to quantify ischemic tolerance for detecting delayed ischemic stroke. Materials and Methods: Forty-one patients who underwent BTO for the internal carotid artery were included.

Preoperatively estimated graft flow rate contributes to the improvement of hemodynamics in revascularization for Moyamoya disease
Moyamoya disease is a cerebrovascular disease that is characterized by chronic progressive stenosis of the terminal portion of the internal carotid artery (ICA) on both sides of the brain, which results in an abnormal vascular network of the collateral pathways at the base of the brain.1,2 Therefore, patients with Moyamoya disease have a decreased cerebral blood flow (CBF) and reduced cerebral perfusion pressure,3 which can result in ischemic and/or hemorrhagic stroke. This hemodynamic condition can be evaluated using positron emission tomography (PET) or single-photon emission computed tomography (SPECT) as the gold standard procedure.

Pediatric Case of Life-Threatening Stroke Caused by Reversible Cerebral Vasoconstriction Syndrome with Spontaneous Cervical Internal Carotid Artery Vasospasm: A Case Report
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by acute and severe headache, referred to as thunderclap, and transient segmental cerebral arterial vasoconstriction. The diagnostic criteria include 1) thunderclap headache with or without neurological deficits or seizures, 2) uniphasic course without new symptoms lasting for more than a month after clinical onset, 3) no evidence of aneurysmal subarachnoid hemorrhage, 4) normal or near-normal cerebrospinal fluid analysis findings, 5) multifocal segmental cerebral artery vasoconstriction on either catheter angiography or, indirectly, computed tomography ...

Volumetric White Matter Hyperintensity Ranges Correspond to Fazekas Scores on Brain MRI
Leukoaraiosis presents as white matter hyperintensities (WMH) on magnetic resonance (MR) imaging. It is thought to originate from decreased vascular supply to axons with an accompanying loss of axonal integrity. WMH have been found to be more prevalent in older patients, especially in those with neurodegeneration from Alzheimer's disease (AD) or stroke.1-6A visual categorization method named the Fazekas scale was developed in order to compare white matter disease burden on computed tomography scans between patients experiencing normal aging and those with AD.

Large Vessel Occlusion Sites Affect Agreement Between Outputs of Three Computed Tomography Perfusion Software Packages
Computed tomography perfusion (CTP) data are important for hyperacute stroke decision making. Available comparisons between outputs of different CTP software packages show variable outcomes. Evaluation for factors associated with agreement between the volume estimates is limited. We assessed for differences in core and penumbra volume estimates of three CTP software packages – AutoMIStar, RAPID, and Vitrea – and analyzed factors associated with agreement between the volume estimates.

Endovascular Revascularization of Multi Segment Chronically Occluded ICA
This case report describes a novel endovascular method for treating chronically occluded internal carotid artery (COICA). The patient is a 55-year-old male with vascular risk factors who presented to an outside institution with right-sided weakness and dysarthria, was diagnosed as having a stroke, and discharged with medical management. The patient's symptoms failed to improve throughout the week prompting him to visit another outside institution, where computed tomography (CT) angiography showed bilateral occlusion of the ICAs at their origins extending intracranially.

Endovascular Thrombectomy Reduces Risk of Poor Functional Outcomes in Patients Presenting within 0-6 Hours with Large Ischemic Core Volumes on Computed Tomography Perfusion
Large vessel occlusion (LVO) stroke patients presenting with large ischemic core volumes (LICVs) on acute imaging have worse outcomes compared to those with smaller ischemic core volumes1 However, endovascular thrombectomy (EVT), compared with medical management (MM), may still be beneficial in this population according to a meta-analysis of patient-level data from early window randomized thrombectomy trials1 and a systematic review of patients presenting with LICVs on computed tomography (CT) or computed tomography perfusion (CTP)2
