Abstract

This pictorial review highlights key radiological signs integral to diagnosing neurovascular conditions. By presenting a curated collection of imaging examples, it emphasizes the characteristic features of various conditions observed on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain and spinal cord. Inspired by familiar imagery from everyday life, these signs function as educational tools and memory aids, enhancing medical professionals' ability to recognize and understand cerebrovascular pathologies, including developmental, ischemic, hemorrhagic, and neoplastic processes. This gallery of signs aims to deepen awareness of neurovascular imaging and support radiologists in achieving accurate and timely diagnoses in clinical practice.

Bag of worms sign. 54 year old male with large cerebral arteriovenous malformation. CT angiography of the Circle of Willis 3D volumerendered reconstruction shows that the arteriovenous malformation is primarily supplied by the right posterior cerebral artery (PCA) (red arrow in 2a) and drains via the vein of Galen and straight sinus (blue arrow in 2b).
