Pneumoperitoneum vs Pseudo-Pneumoperitoneum aka Chilaiditi Sign
It mimics pneumoperitoneum and it is thus important to diagnose it correctly so that the patient doesn’t have to undergo unnecessary investigations or procedures.
The presence of the haustra prove that this is due to interposition of the large gut (commonly the transverse colon) between the liver and right hemidiaphragm.
