  Fig. 1 (A) Liver dynamic magnetic resonance imaging. Axial unenhanced fat-suppresed T1-weighted image shows the variable signal intensity of the multiple locules. (B) Axial fat-suppresed T2-weighted image shows the grape-shaped multicystic lesions with high signal intensity. (C) Axial gadoxetic acid-enhanced T1-weighted image shows multiple and thin enhancing septa without communication between bile duct and cystic lesion.

  Fig. 2 Gross specimen image of a resected multilocular cystic lesion of the liver. The mass demonstrates an old hemorrhage, degenerated fluid, and cholesterol granuloma.

• 

  Fig. 3 (A) Microscopic images show irregular cystic spaces with underlying fibrous stroma (hematoxylin and eosin [H&E], ×12.5). (B) Multiloculated cysts lined with cuboidal or flattened biliary type epithelial cells (H&E, ×200; yellow arrow). (C) Degenerated fluid and cholesterol granuloma (H&E, ×100; red arrow). (D) Focal papillary projection (H&E, ×100; blue arrow).
