ACCORDING TO Swellengrebel and Sterman,1 human cysticercosis is probably always due to infection with Cysticercus cellulosae, the bladderworm of Taenia solium. Human infection with C bovis, the bladderworm of T saginata, has never been described because cattle are practically the only animals that serve as its intermediate hosts. On the contrary, T solium has at least two intermediate hosts, namely, pig and man. Thus, man serves as definitive host as well as, in some instances, the intermediate host of T solium. As definite host, man harbors the adult tapeworm; and as intermediate host he harbors the bladderworm or cysticercus. In Holland, human infection with T solium is extremely rare and porcine cysticercosis is no longer found in indigenous hogs. During the last decades, human cysticercosis in this country has been diagnosed in foreigners only. The only previously described case of histologically proven intraocular cysticercus in Holland dates from 1901.
