Figure legends
Figure 1 – Abdominal radiograph in seated position shows
gastric distension with air-fluid level (asterix), pneumobilia (arrow)
and an ectopic calcified gallstone in the lower right quadrant
(arrowhead) – Rigler triad.
Figure 2 - Coronal image of contrast-enhanced abdominal CT
shows marked gastric stasis and distension conditioned by a gallstone
(arrowhead) in the level D3 of duodenum and the cholecystoduodenal
fistula (arrow). CT also depict pneumatosis of the gastric wall (open
arrowhead) and associated pneumoportia (open arrow), suggesting ischemia
due to acute massive distension.
