case_images: Cholecystoduodenal fistula. Axial CT slices without contrast. In image A, there is a lack of definition of the anterior wall of the gallbladder body and the first portion of the duodenum, suggesting a cholecystoduodenal fistula (orange arrow). In image B, the presence of mineralized calculus (green arrow) and gas (asterisk) in the gallbladder lumen can be identified.. CT: computed tomography

case_images: Computed tomography (CT) revealed signs of jejunal obstruction due to an oval formation with multilayer mineralization at the periphery measuring 38 mm; another spheroid-like structure measuring approximately 26 mm in the lumen of the upstream jejunum; gallbladder with two stones and gas inside, as well as in the cystic duct and bile ducts of the left lobe, assuming origin from the gallbladder; and a vague and discrete thickening of the anterior wall of the vesicular body and the first portion of the duodenum, changes that in the current clinical context could suggest a cholecystoduodenal fistula with migration of larger stones found in the jejunal lumen (Figure 1 and Figure 2).
