[Radiologic signs in the colon in disease of the gallbladder (author's transl)].

Acute and chronic inflammation of the gallbladder may simulate pseudotumors of the right half of the colon; this may at times be obvious on straight films of the abdomen. Analysis of the changes of relief in contrast-examinations of the colon will lead to the correct diagnosis. Inflammatory reactions of the colon mostly appear near the mesocolic tenia. Cholecystocolic fistulae are mostly due to perforation of stones, only exceptionally to tumors. Adhesions appear to be the precondition for malignant infiltration and stoneperforation.
