Acute calculous cholecystitis in a patient with suprahepatic gallbladder, hepatic hypoplasia and Chilaiditi's sign.

Chilaiditi's sign is the interposition of small bowel or colon between the liver and diaphragm. This incidental finding is seen in 0,025-0,28% of the chest and abdominal radiographies. Predisposing factors include the absence, laxity or elongation of the suspensory ligaments of the transverse colon, redundant colon or elevation of the right hemidiaphragm. Atrophy or hypoplasia of the liver is an uncommon cause of this radiological sign. On the other hand, suprahepatic gallbladder is the most infrequent location of gallbladder ectopies (0,026-0,7%). It is associated with an abnormal development of the right liver lobe such as agenesis, hypoplasia or atrophy. We present the case of a 73-year-old man with Chilaiditi's sign, hepatic hypoplasia and acute calculous cholecystitis in an ectopic suprahepatic gallbladder.
