Figure 2. . Histologic section through Taenia crassiceps tapeworm larvae removed from the cerebellum of a 51-year-old woman, Germany. A) Section through parasite body showing multiple connected bladders (asexual buddings) at the caudal end. Original magnification ×20. B) Transverse section through the parasite’s protoscolex showing numerous hooklets, similar to T. solium tapeworm larvae. Original magnification ×40. Like the Taenia solium tapeworm that causes cysticercosis, and in contrast to different tapeworms that cause coenurosis (T. [Multiceps] multiceps, T. [Multiceps] serialis) or echinococcosis, the T. crassiceps tapeworm has only 1 invaginated protoscolex, but it is on a very long neck (Cysticercus longicollis). The hooklets of T. crassiceps tapeworms are larger than those of T. solium tapeworms and have a larger blade length than handle length. The small hooklets measure 123 µm; the large hooklets measure 167 µm.
