Microscopic examination of the fluid inside of objects revealed the following:

    Echinococcus and I don't know how to tell granulosus from multilocularis. Great pictures and really good and fun blog.

    Echinococcus hydatid cysts - I think E. gransulosus given the locaction and morphology of the cysts (am I right in thinking singular cysts like this are indicitive of E. granulsosus wheras multilocularis cysts would look like what it says on the tin - ie, have mulitple lobes/buds?) - either way, beautiful picture of a protoscolex in hydatid sand :D

    I agree, Echinococcus cysts.

    It's E. granulosus. E. multilocularis wouldn't be able to be excised as a well-delineated cyst - the growths would have poor boundaries and would intercalate with the surrounding tissue.

    Echinococcus hydatid cysts. One protoscolex and several hooklets seen. Most likely E. granulosus.

    E. granulosus my choice too - but because of cyst morphology rather than liver location. E. multilocularis cysts are also mostly in the liver.
