Present paper describes the findngs of three cases what appeared to be the case of "Porcelain gallbladder" showing the X-ray picture similar to gall stones in the resected bladder and Calcium deposite on the bladder wall. It was in 1926 that "porcelain gallbladder" case was first reported by Florcken. Since then there appeared reports of such cases by Yamamoto, Niizuma and others, but this is a relatively rare diseases. It is sometimes accompanied by gall stones and in other cases without any stones. In the diagnosis of this disease by X-ray it is possible to identify this case by the roentgenograms of affected field and also by tomography of that region. We are able to examine three cases that we encountered by simple X-ray pictures, X-ray pictures with contrast medium as well as by tomographic pictures of the affected region. Some discussion was made comparing the findings of our cases with those available in literature.
