Case Discussion
The Mercedes-Benz sign describes a star-shaped pattern of gas-fissuring within gallstones initially described on an abdominal radiograph, but now more commonly identified on CT.
The name is also given to the clinical appearance of a surgical scar from an incision used for major hepatobiliary surgery.
