Cestodes aka a tapeworm. S. mansoni, S. ranarum, S. mansonoides, S. erinaceieuropaei, and S. erinacei, Sparganum proliferum
Eating raw frogs and snakes or drinking contaminated water. The normal host is the dog and cat and if you eat the eggs, found in their poo, you can get the disease. Can live up to 20 years in people.
More common in Asia and Africa (PubMed).
Mass effect in whatever tissue it settles in.
To quote the CDC "Surgical removal is the treatment of choice for sparganosis. Generally, treatment with mebendazole, albendazole, or praziquantel is not effective to treat infection with these larvae. In rare cases of proliferative sparganosis, prolonged treatment with mebendazole and praziquantel have been used in addition to surgical removal with mixed success."
Evidently there are also cases from using the flesh of an infected frog or snake as a poultice on open wounds. Can you say ick?
