Rolling in the Deep: Imaging Findings and Diagnostic Pearls in Gallstone Ileus

Figure 8

Contrast-enhanced computed tomography in a surgically proven case of gallstone ileus, in which the presence of an isodense gallstone (white arrows in (a) and (b)) in the jejunum was overlooked. Sagittal reformatted image (b) demonstrates a focal widening of the jejunum just before the transition point; this mass effect is associated with the presence of different attenuation values compared with the fluid-filled proximal bowel.
