The abdominal x-ray was performed with clinical concern for a small bowel obstruction.
In fact, the x-ray shows a large density in the region of gall bladder.
The patient went onto have an ultrasound scan of their abdomen which revealed a 2.2 cm stone stuck in the cystic duct with features of cholecystitis.
Pay attention to calcific densities on an abdominal x-ray!
