The interposition of the colon or the small intestine between the liver and the diaphragm otherwise called Chilaiditi syndrome remains a rare condition. Its incidence varies between 0.025% and 0.28% according to recent literature and is only found incidentally on diagnostic imaging. Hence, it constitutes a classic pitfall in the diagnosis of false right pneumoperitoneum. We deem interesting to report a case of Chilaiditi syndrome in a 44-year-old patient with no significant history who was admitted at emergency department for abdominal trauma following a road accident.
