case_images: (a) Axial slice from a recent CT pulmonary angiogram used for comparison demonstrates a gallbladder normal in size and position (arrow). The axis of the gallbladder from neck to fundus is highlighted (double-sided white arrow). (b) There is a dramatic change in the anatomical position of the gallbladder (arrowhead) with a horizontal lie and grossly distended state:two signs of gallbladder volvulus. The striking change in the axis (double-ended white arrow) is significant.
