[Chilaiditi syndrome].

The paper deals with a patient who was admitted through the surgical emergency service under the suspicion of subphrenic abscess. From the moment of admittance the patient was carefully followed. Laboratory tests were repeated several times. The following examinations were performed within a very short period of time: a posteroanterior X-ray of the chest and both subphrenic spaces, an ultrasonogram of the upper abdomen, a CT scan of the upper abdomen, roenthgenography of the gastroduodenum with gastrografin, an esophagogastroduodenoscopy and irrigography. Apart from the interposition of the colon between the liver and the diaphragm, no other pathological changes were found. Clinical follow-ups of the lungs and the abdomen were normal. The patient was discharged in a good general condition.
