Radiological Profile of 18,430 Vascular Anomalies: Incidence and Demographic Distribution in an Adult Population.

Background: Most studies on focusing on the prevalence of vascular anomalies are either aimed to determine the individual occurrence of a specific type among known bearers of abnormalities or propose an estimation of prevalence for the general population by extrapolating from the paediatric population. In this scenario, we intended to assess the profile of vascular anomalies in a group of patients subjected to imaging studies, throughout a long period of time, to evaluate the frequency of abnormal findings in a consecutive, nonselected population.

Methods: This is a retrospective review of 996,569 computed tomography and magnetic resonance studies between 2009 and 2019.
