Paragonimus kellicotti
An 8 month old dog from MS died suddenly from pneumothorax. This is the lung tissue
from necropsy, observe many cysts. The dog ingests many mammalian and aquatic
wildlife. What species?
Calcareous corpuscles, cestode

You also see many mineralized structures in the parenchyma. What are these
mineralized structures called? What type of parasite?
