The Mercedes-Benz describes a star-shaped pattern of gas-fissuring within gallstones initially described on abdominal radiographs. Fissures, usually fluid-filled, are present in close to 50% of gallstones. Less than half of these fissured gallstones contain some amount of gas . The radiolucency caused by the gas usually appears in a triradiate pattern, mimicking the Mercedes-Benz logo.
