A repeat 3-view obstruction series (Figure 1(a)) was obtained after admission because of continued vomiting. CT scan revealed a uniformly thin walled fluid attenuation mass in the epigastric region, which did not opacify with contrast, suggesting a duplication cyst or a choledochal cyst (see arrow in Figure 1(b)). Correlation with ultrasound was recommended, to evaluate "gut signature" or continuity with the biliary tract.
