Is It a Diaphragmatic Hernia?

Chilaiditi's syndrome is a symptomatic hepato-diaphragmatic interposition of a colon and/or small intestine. When it is asymptomatic, it is called Chilaiditi's sign. It is a benign condition that may mimic other concerning diagnoses on radiography, such as diaphragmatic hernia or pneumoperitoneum. Computed tomography (CT) is the best imaging tool to assess the diagnosis. We report a rare case of Chilaiditi's syndrome with intermittent dyspnea, suspected on radiography and diagnosed on CT. Nasogastric decompression relieved the patient's symptoms.
