Gallstone ileus, clinical presentation, diagnostic and treatment approach

Figure 3 Contrast-enhanced computed tomography findings in a patient with gallstone ileus. A: Portal phase IV-contrast enhanced computed tomography section reveals air in the hepatic duct (arrow), anterior to a permeable right portal vein (arrowhead); B: Communication between a non-distended gallbladder (arrowhead) and the duodenum (arrow), where presence of air is observed. Fluid-filled dilated jejunum loops and intestinal pneumatosis are seen (short arrow); C: Endoluminal round-shaped calcium-density images (arrows), and dilated small bowel loops (arrowhead) with pneumatosis (short arrow).
