Cysticercus

(sis'ti-ser'kŭs),
Originally described as a genus of bladderworms, now known to be the encysted larvae of various taenioid tapeworms; the generic name is, however, retained as a convenience in referring to the larval encysted forms. See: cysticercus.
Synonym(s): bladderworm
[G. kystis, bladder, + kerkos, tail]

cys·ti·cer·cus

, pl.

cys·ti·cer·ci

(sis'ti-ser'kŭs, -ser'sī),
The larval form of certain Taenia species, typically found in muscles of mammalian intermediate hosts that serve as a prey of various predators; it consists of a fluid-filled bladder in which the invaginated cestode scolex develops.
See also: Taenia saginata, Taenia solium.

cysticercus

The larval stage of many tapeworms. It consists of a head segment with attaching hooks or suckers (scolex) enclosed in a fluid-filled sac. Tapeworm in man is normally acquired by eating undercooked pork or beef containing cysticerci.

cysticercus

the larval form of a tapeworm which grows into the adult when eaten by the primary host, and consists of a SCOLEX inverted into a large bladder. When ingested the outer cyst wall is digested, the scolex everts and the bladder disappears. The scolex attaches to the intestinal wall of the host and a new tapeworm forms with the growth of proglottides. See Fig. 126 .

Neurocysticercosis (NCC) is more commonly seen to involve the brain parenchyma and uncommonly involves the ventricular system and subarachnoid spaces.1 Whereas parenchymal cysticerci can be readily identified on CT and MRI, most authors agree that it is difficult to identify lesions within the cerebrospinal fluid (CSF) spaces.
