A case of complete and permanent interposition of the intestine between the liver and diaphragm (Chilaiditi's syndrome) is reported. Although it was an accidental finding, the hepato-diaphragmatic interposition may be found in persons with gastrointestinal complaints. The diagnosis only can be done through the radiological examination and it can be differentiated between the large and small intestine interposition by a barium enema. Finally references are made by the authors about the history, pathogenesis, possible symptoms and treatment of this syndrome.
