    It's Echinococcosis spp but I don't know if you can tell between granulosus and multilocularis without knowing the history. Also, the protoscolex reminds me of the facehugger from Alien vs Predator. :0

  2. Such a finding like this is so rarely encountered. What springs into my mind is that these are protoscoleces in a hydatid cyst. The invaginated hooklets are clearly visible. Thank you Dr. Pritt for the beautiful find, this reminds us that the disease though rarely found in the US is still lurking around.

  3. Protoscolex from a hydatid cyst, probably due to Echinococcus granulosus.
