I saw Medusa's head sign and turned to stone

Abstract

Developmental venous anomalies (DVAs) are characterized by many radially oriented medullary veins surrounding a central draining vessel. When the imaging plane is perpendicular to the central vessel, these medullary veins resemble Medusa's head of snakes. Medusa's head sign, or caput medusae, can be appreciated on contrast enhanced CT scans and MRIs of the brain and is highly indicative of a DVA.
