This week's case is another histopathology finding from an eye. The entire orbit was removed because of the presence of a parasitic cyst. You can see the digital slide HERE. Identification?
Here is a screen shot of the digital slide:

A fun case for all of your Parasitology 'pupils' :-)
I spy with my eye -- a pupil guesses cysticercosis.
CA guessing.
Eye, Eye Captains Blaine an CA. Looks like a case of Ocular Cysticercosis caused by Taenia solium.
OK, the authorities in the field have spoken. Following their lead, I can quote “ I once was blind, but now I see”: I believe seeing two suckers, the cross section of the “crown of thorns” or rostrum of the inverted scolex, and the highly convoluted spiral canal.
Thank you everyone for the teaching,

I'm just mildly disappointed i didn't get to chime in with that immortal garage/surf rock classic...
Loa Loa, oh no, you gotta go,
yeah, yeah, yeah,
yeah, yeah, baby
Loa Loa, oh baby, you gotta go
I said you gotta go now
Let's hustle on out of here
Let's go!
with a B side of "Take Me to the River" for Onchocerciasis...
Agree with cysticercosis. I think Florida Fan is right in the description, regarding the suckers and hooklets.
time for my 'serious' answer (if I ever give such a thing LOL).
Yup, ocular cysticercosis caused by T. solium, as indicated by a single protoscolex. Coenurus caused by a zoonotic Taenia is also possibly, but coenuri have multiple protoscoleces, as do hydatid cysts of Echinococcus. Sparganosis is another cestode infection that can manifest in the eyes, but they do not produce protoscoleces at all.
