Thanks, ICU, for posting this. Years ago when I was studying helmenthology it was known that Tapeworm cysts could rarely be found in unusual areas, the brain in particular. There was no mention of canine tapeworms, I guess they just assumed that these cysts were from the more common Tapeworms which occur in the human intestine.
I wonder if using herbal (quassia) or supplement (CoQ) treatment and a Zapper might kill the worms in the cysts or if in this case specific treatment with meds would be the best treatment.
