Abdominal contrast enhanced CT showed an intrahepatic multicystic mass in the segment VI of the liver. (A) Calcification was observed in dilated ducts (plain phase arrow); (B) The enhancement of the septa and peripheral wall within the cystic lesion (arterial phase); (C) The lesion showed a low-density honeycomb-like appearance (venous phase).

Abdominal CT revealed a multilocular cystic lesion in the segment VI of liver (Figure 1C). Interestingly, small calcification was found on precontrast CT (Figure 1A) and the septa and peripheral wall within the cystic lesion showed mild enhancement on postcontrast (Figure 1B).
The grey-white and typical multicystic appearance of the lesion was shown during laparoscopic operation (arrow).

Laparoscopic complete resection of the lesion was performed (Figure 2).
Histological findings of the resected lesion tumor (Hematoxylin and eosin staining). (A) The lesion consisted of dilated cystic ducts surrounded by the connective tissue of smooth muscle and capillaries (x20); (B) Ducts are lined by columnar epithelium (x100).

Histopathological findings of formalin fixed paraffin embedded tissue on revealed periductal glands surrounded by connective tissue containing smooth muscle and small blood vessels but no ovarian-like stroma (Figure 3).
