Multiple calcifications in right hypochondrium, with radiolucent edge and radiolucent center, polygonal morphology.
Magnified image: some of these calcifications have a linear distribution, similar to the logo of a well-known global automobile brand. This finding is more evident in the lithiasis localized in the upper right corner of the image.
Although the sign of the Mercedes-Benz is a sign initially described in conventional radiography, most of the images available today are by CT.
In this patient we show the classic appearance in radiography, although it is a inconstant finding in cholelithiasis and its meaning is more anecdotal than clinically relevant.
