What is your diagnosis? (29)

%%RATING%%

  Histopathology confirmed it was a parasitic vesicle. Given its morphology and location, adhered to a serous membrane, it is, most likely, a Cysticercus tenuicollis vesicle, the larvae or metacestode of Taenia hydatigena.     Not to be confused with porcine cysticercosis (caused by Cysticercus cellullosae, metacestode of Taenia Solium, a zoonosis that has been eradicated from our country). See post about cysticerci in pig carcasses.
