AbstractLarge gallstones could erode through gallbladder wall to nearby structures, causing fistulas, gastric outlet obstruction and gallstone ileus. They typically occur in elderly patients with comorbidities carrying therapeutic challenges. We present a case of a middle-aged woman who was thought to have symptomatic cholelithiasis. Extensive adhesions precluded safe cholecystectomy. While hepatobiliary iminodiacetic acid scan and magnetic resonance imaging with cholangiopancreatography (MRI-MRCP) failed to visualize the gallbladder, computed tomography (CT) was consistent with cholecystoduodenal fistula. A very large gallstone was seen endoscopically in the duodenum, which was broken down into pieces using a large stiff snare.

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.
