What is your diagnosis? (40)

%%RATING%%

The image we can observe in the binocular loupe corresponds to the double crown of hooks characteristic of the Cysticercus tenuicollis scolex (larval phase of Taenia hydatigena). Also known as visceral cysticercosis, it is common in goats and sheep but can also be seen in pig, both domestic and wild boar. This lesion should not be confused with porcine cysticercosis caused by Cysticercus cellullosae (larval phase of Taenia solium, which is zoonosis) in this case the lesions would be found as cysts in the musculature.
