Chilaiditi described the interposition of the distal right and transverse colon between the liver and the right hemidiaphragm in 1910.


Prolonged therapy with a psychotropic medication may be a risk factor for the interposition.


If the finding is incidental and not causing symptoms, then it is refered to as Chilaiditi's sign.


The presence of the symptoms due to the colonic location is called Chilaiditi's syndrome. Signs and symptoms may include:

(1) abdominal pain

(2) constipation

(3) abdominal distention

(4) nausea and vomiting

(5) anorexia


The patient may also develop complete bowel obstruction due to volvulus.


The appearance on abdominal X-ray may be misinterpreted as pneumoperitoneum.
