Clinical and radiological characteristics of calcified cerebral embolism: a large case series including 242 calcified cerebral embolism.

Introduction: Radiological calcified cerebral embolism (CCE) characteristics have been reported in small case series. Our aim was to describe clinical and radiological CCE characteristics in a large number of CCE and to compare characteristics between different patient groups.

Methods: Characteristics of 79 stroke patients with CCE were analyzed retrospectively.

Relationship between hyoid-carotid distance, hyoid position and morphology and degree of stenosis and associated stroke: Hyoid-carotid relationship.

Background: Pressure on carotid artery by hyoid bone may influence plaque formation. We studied CTA-based hyoid-carotid anatomical interaction and its relationship with carotid stenosis degree and stenosis-related stroke.

Methods: We retrospectively analysed pre-operative CTA of 205 consecutive adults having undergone carotid endarterectomy (CEA) for asymptomatic or symptomatic stenosis.

Diagnostic Accuracy of Posterior/Anterior Periventricular WMH Ratio to Differentiate CAA From Hypertensive Arteriopathy.

Background: Periventricular white matter hyperintensities (PVWMHs) in cerebral amyloid angiopathy (CAA) have been reported posterior predominant using semiautomated segmentation method and logarithmic transformation. We aimed to compare PVWMH extent and posterior/anterior distribution between patients with CAA and patients with hypertensive arteriopathy with radiological tools available in daily practice.

Methods: We retrospectively analyzed confluent PVWMH directly adjacent to lateral ventricles on axial FLAIR (fluid-attenuated inversion recovery) from 108 patients with CAA and 99 patients with hypertensive arteriopathy presenting with hemorrhage-related symptoms consecutively recruited in our stroke database (Nîmes University Hospital, France) between January 2015 and March 2022.

Acute phase supra-aortic intraluminal thrombus signal changes on magnetic resonance angiography: A case series: Intraluminal thrombus signal changes on MRA.

Background And Objectives: Intraluminal thrombus (ILT) is a relatively rare cause of stroke. MRI/MRA is increasingly used for stroke patients eligible for acute treatment. Radiological ILT characteristics have never been studied systematically on MRA.

Cerebellar Superficial Siderosis in Cerebral Amyloid Angiopathy on 1.5T T2*-Weighted Imaging.

Background: Cerebellar superficial siderosis (SS) has been recently reported to be present in about 10% of both hereditary and sporadic cerebral amyloid angiopathy (CAA) on 3T MRI using primarily susceptibility-weighted imaging.

Objectives: Our aim was to assess cerebellar SS in sporadic CAA patients using 1.5T T2*-weighted MRI and to evaluate possible underlying mechanisms.
