Ciliated hepatic foregut cyst: an increasingly diagnosed condition.

Ciliated hepatic foregut cyst is a rare foregut cystic developmental malformation. It presents as a solitary cystic lesion in segment four of the liver. Histologically, it consists of four distinct layers; namely, the inner ciliate columnar epithelium, subepithelial connective tissue, smooth muscle layer, and an outer fibrous layer. Usually asymptomatic and detected incidentally, other modes of presentation can include portal hypertension, obstructive jaundice, and development of malignancy. We present a case of a young asymptomatic woman with a complex cyst in segment four of the liver, who underwent a laparoscopic resection, focusing our discussion on the review of the literature and the diagnostic dilemma encountered in these rare cases.
