I vote trichinosis (without looking up size) on the basis of muscle and no clever hx.
evidently nematode, the question is, Trichinella (I see no significant nurse cell boundary), Baysilascaris (midwest USA and Racoons?) or another case of Toxocara ocular migrans? I'm not sure how to go out telling them apart and cant think of any other species which particularly like eyes...
I have no clue. But this is the coolest sight I have ever seen. Can we perhaps post some stuff too.
how about cysticercosis?
