At histological examination, both cysts had four typical layers of ciliated hepatic foregut cyst, composed of inner ciliated, pseudostratified, columnar epithelium; subepithelial connective tissue; smooth muscle layer; and an outer fibrous layer (Figures 2(a) and 2(b)). The fibrous layers are stained green with Masson trichrome stain (Figure 2(c)).
