Slither of free gas under the right hemidiaphragm.

Case Discussion

The erect chest x-ray can identify relatively small volumes of pneumoperitoneum provided the patient is in the erect position for a sufficient time for it to navigate under the diaphragm.

CT abdomen typically follows this finding with a view to identifying the cause prior to a laparotomy.
