Chilaiditi’s sign: hepatodiapragmatic interposition of the small intestine

Chilaiditi’s sign or hepatodiaphragmatic interposition of bowel seen on an erect chest radiograph can mimic pneumoperitoneum. The presence of plicae circulare or haustrations is necessary to differentiate this condition from pneumoperitoneum. When this radiological sign is accompanied by a broad range of gastrointestinal symptoms, the condition is known as Chilaiditi’s syndrome. In a majority of the cases, Chilaiditi’s syndrome is managed symptomatically. We present a case of incidentally detected Chilaiditi’s sign in a 73-year-old asymptomatic male.
