Fig. 3.

A 78-year-old man with dropped gallstones (case 3). Two irregular-shaped masses with multilocular fluid collection and thick septation that invaded the liver, abdominal wall, and colon were seen in the right Morrison's pouch (a: arrow) and the gallbladder fossa on contrast-enhanced CT (b: arrows). The hypoechoic mass in the right Morrison's pouch invaded both the liver parenchyma and abdominal wall on US (c: circle). The hypoechoic mass in the gallbladder fossa invaded the liver parenchyma and revealed a hyperechoic lesion on US (d: arrow).
