An abdominal computed tomography (CT) imaging demonstrated a left hepatic multiloculated cystic mass measuring 9.5 x 8.6 cm; local cystic wall could show high-intensity shadows projecting into the intracavitary, less clear boundaries, and dilated left intrahepatic biliary tree.

An abdominal computed tomography (CT) imaging demonstrated a left hepatic multiloculated cystic mass measuring 9.5 x 8.6 cm; local cystic wall could show high-intensity shadows projecting into the intracavitary, less clear boundaries, and dilated left intrahepatic biliary tree (Figure 1).
Magnetic resonance cholangiopancreatography (MRCP) demonstrated a multiloculated cystic lesion measuring 9.4 cm and cystic dilated common bile duct 8.6 cm in diameter, and the dilation of both right and left intrahepatic bile ducts lacked asymmetry.

Magnetic resonance cholangiopancreatography (MRCP) demonstrated a multiloculated cystic lesion measuring 9.4 cm and cystic dilated common bile duct 8.6 cm in diameter, and the dilation of both right and left intrahepatic bile ducts lacked asymmetry (Figure 2).
On gross examination, the resected left liver specimen showed a multilocular cystic lesion measuring 11 x 8 x 3.5 cm, covered with bullate nodules on the cutting surface.

On gross examination, the resected left liver specimen showed a multilocular cystic lesion measuring 11 x 8 x 3.5 cm, covered with bullate nodules on the cutting surface (Figure 3).
Intrahepatic biliary lesion was lined by a single layer of cuboidal and columnar epithelial cells, arrangement of papillary and adenoid, and some epithelial hyperplasia with severe atypia were observed microscopically.

A stroma with a dense layer of proliferating fibrous tissue was underlying the epithelium (Figure 4).
