What a beautiful case. The liver location and appearance of the protoscolices indicate a hydatid cyst. We can clearly see the crown of hooklets in the invaginated cyst in the next to last picture. The last picture shows a loose hooklets. My vote in this case would be Echinococcus granulosus sensu lato.
