Double vertebral arteries associated with a persistent primitive lateral basilovertebral anastomosis: A rare embryological configuration

Vertebrobasilar vascular anomalies arise from disturbances during the embryological development of the longitudinal neural arteries (LNAs), the proatlantal artery of Padget–Arey (ProA), and the primitive lateral basilovertebral anastomosis (PLBA) [ 1 , 2 ]. We report a rare verte...

Variation in meningioma recurrence risk estimates across observational cohorts: the influence of calendar time, WHO classifications, geographical settings, and healthcare systems

Abstract Purpose Recurrence risk estimates underpin meningioma research, including molecular classification and clinical trial benchmarking, yet are often based on retrospective or historical data. The aim of this study was to assess the variation of recurrence risk estimates acr...
