Judging from the clinical site brings up a positive note for hydatid cyst. On a closer look, the hooklets are clearly visible as well as the numerous calcarous particles. Since there is one cyst, the indication is that the agent is Echinococcus granulosis.
What an interesting case to begin the year with.

Protoscolices of Echinococcus granulosus sensu lato.

Agree with Florida Fan: Echinococcus spp hydatid cyst/protoscolex (educated guess: E. granulosus complex). Echinococccus ssp cause cystic echinococcosis (CE) or hydatidosis. The liver is the most frequent location of echinococcal cysts (approx. 70% of cases). The lungs are the second most common location.
