Pneumoperitoneum. a, b Normal aspect of the liver using a transverse view at the anterior axillary line. c When air is present in the abdomen, it will typically accumulate in the non-dependant region just anterior to a portion of the liver. d When the ultrasound beam is positioned over this area, the normal acoustic aspect of the liver will be followed by a sharply demarcated acoustic shadow. The term “liver sign” can be used to describe this abnormal air-liver interface.
