Chilaiditi sign secondary to a right renal agenesis

Abstract

Chilaiditi’s sign is a rare radiological finding in which a portion of the colon or small intestine is interposed between the liver and right hemidiaphragm. Associated to pain, it is called Chilaiditi syndrome. We describe the case of a patient who was admitted to our radiology department to release a body-computed tomography (CT) for its breast cancer extension assessment. We incidentally discovered a colic hepato-phrenic interposition related to a Chilaiditi sign associated with right renal agenesis. In this case report we treated Chilaiditi sign can exist without Chilaiditi syndrome, as it could be associated with other pathologies and abnormal anatomic malformation like renal agenesis.
