Cerebrovascular anomalies can present many challenges to radiologists in training due to shared features of their appearances. Knowing the distinguishing features on different imaging modalities is key in diagnosis due to the variance in age, demographics, and clinical presentation of vascular anomalies of the brain. While some are asymptomatic and incidental findings, there are other anomalies that can be life-threatening, so it is important to identify and diagnose these lesions to provide appropriate patient care.

Educational Goals / Teaching Points
The goal of this presentation is to describe the imaging appearances of various forms of cerebrovascular malformation and unique imaging features that help differentiate one vascular anomaly from another, in a succinct manner. More specifically, the features of each condition will be described, such as risk factors, demographics, and management of these lesions.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
In this educational exhibit, we will review imaging findings of several cerebrovascular anomalies. We will present cases illustrating both high and low flow lesions such as arteriovenous malformation (AVM), arteriovenous fistula (AVF), vein of Galen malformation, dural AVF (dAVF), developmental venous anomaly (DVA), cavernous malformation (cavernoma), capillary telangiectasia, and sinus pericranii.

Radiologists should be familiarized with the range of cerebrovascular anomalies to ensure that patients are managed correctly, whether the abnormality requires emergent or no intervention.
