Surgical removal of a subretinal proliferating cysticercus
of taeniaeformis crassiceps.
In the brain parenchyma the larva undergoes an orderly life cycle, from cysticercus
4) Ultrasonography demonstrates Cysticercus
organisms as cystic structures with an eccentric nodule that represents a scolex; such a finding is pathognomonic of cysticercosis.
Use of urea (5M) induced tertiary conformations of these proteins improved sero-detection on immune blots of cysticercus
antibodies among patients with solitary cyst infections to 71% from 62% using antigens not treated with urea.
Cysticercosis is an important parasitic zoonosis, caused by the infection of Cysticercus
cellulosae, the larval stage of Taenia solium.

23) Finally, when the larva dies, the cysticercus
becomes calcified, edema lessens, and contrast-enhancement resolves, (24) although there are rare reports of recurrent pericystic edema after calcification (Fig.
The life cycle is completed when humans eat undercooked pork infested with viable cysticerci, and a cysticercus
enters the small intestine and develops into an adult tapeworm.
NCC occurs when the cysticercus
penetrates the blood-brain barrier into the central nervous system (CNS).
The larval parasite that develops is then called a cysticercus
, or bladder worm.
The removed cyst showed the characteristic macroscopic and histologic features of a cysticercus
bladder wall (Figure, panels E, F).
In sheep, a major cause of carcass rejection is Cysticercus
Ovis: in just one large Welsh abattoir in 2011/12, the equivalent of 275 lambs, weighing 19kg, were rejected due to C.
