Cysticercosis - helminthiasis caused by the larvae of pork tapeworm - tsistitserki, or Finns (Cysticercus cellulosae). Tsistitserki - transparent bubbles size 6-20x5-10 mm; their inner wall attached screwed into the head with four suction cups and a double crown of hooks. Muscle tsistitserki have elongated shape (Fig. 1), in the connective tissue - rounded.
Human infection cysticercosis happens if swallowed nuclei (oncospheres) pork tapeworm with foodcontaminated with the faeces of infected pork tapeworm person. Cysticercosis can be a complication of intestinal tenisa, which Mature segments of the helminth thrown into the stomach during antiperistaltic intestines. In the stomach segments digested, and from the uterus are exempt eggs of the parasite with oncospheres. Tsistitserki are localized in different body organs; more often they are found in brain and spinal cord, to the eye, sometimes in the skin, muscles and other tissues (Fig. 2).
The clinical picture is different depending on localization Finn and intensity of infection. In the localization of tsistitserki in the brain syndromes observed: epileptiform, neoplastic, mental, meningeal, with the defeat eye - impaired vision, sometimes blindness.
The diagnosis. Recognition of cysticercosis eyes possible through ophthalmoscopy. Tsistitserki localized in the muscles and the skin and subcutaneous tissue, can be detected by palpation and biopsy; calcified tsistitserki detected by x-ray. Cysticercosis brain is diagnosed based on the clinical picture, the data of x-ray and research cerebrospinal fluid. Utility method for diagnosing is a reaction of binding complement to the antigen of tsistitserki.
Treatment of cysticercosis only surgical and symptomatic.
The basis of prevention is to combat tenisom by sanitary-educational work, thorough veterinary-sanitary control over pork carcasses, and treatment of patients.

Cysticercosis (cysticercosis) is a disease associated with parasitizing in the tissues of animals and humans tsistitserka, or Finns,the larvae squad Cana.
Cysticercosis is caused Cysticercus cellulosae - the larva of the pork tapeworm (Taenia solium). Cysticerci pork tapeworm - ovoid shape of the bubble with transparent walls; one side of his protruding inside and ends head with four suction cups and aureole of hooks. The development of tsistitserki lasts 2-3 months. they tissue parasites.
Cysticercosis person occurs everywhere. Morbidity associated with the presence of pigs infected with measles and infect human tenisom, which in turn leads to cysticercosis humans and pigs. Human infection cysticercosis occurs when ingestion of eggs pork tapeworm with food, water and soil, contaminated faeces patients with intestinal adult worms.
In the human stomach oncospheres under the influence of gastric juice exempt from shells, penetrate using hooks in the wall of the stomach or intestine and are carried by the blood stream to the various organs and tissues, where develop in the tsistitserki. Cysticercosis is also the complication of the intestinal tenisa, which at the time antiperistaltic bowel movements tapeworm can zabrasyvaya in the stomach, where the segments are digested, and from the uterus are exempt parasite eggs with oncospheres.
In diagnosis of cysticercosis brain, in addition to the clinical symptoms and history, is widely used in laboratory and x-ray methods. The most valuable research spinal fluid, especially the cellular composition (cysticercosis - lymphocytic, as a rule, with the presence of eosinophils); number of cells with repeated punctures usually varies, but is more often from 20 to 60 to 1 mm3. Reaction Lange (gradual discoloration mixture of cerebrospinal fluid with colloidal solution of chlorine gold) for the most part gives a curve, typical for progressive paralysis. In the blood-thirds of patients found eosinophilia. Quite sensitive and specific cysticercosis was RAC with the antigen from tsistitserka or Mature pork tapeworm. In case of positive reaction simultaneously with cerebrospinal fluid and blood diagnostic value it greatly increased.
Detection of Taenia solium in the intestine, tsistitserka in the eye, calcified of tsistitserki in the brain or soft tissues, the presence of dense, painless nodes in the skin, subcutaneous tissue, muscles makes Troubleshooting much easier cysticercosis brain (data biopsy these nodes confirm the diagnosis). However, the absence of these signs does not exclude the diagnosis.
Cysticercosis brain should be differentiated tumors (data pneumo - and ventrikulografii) and inflammatory diseases of the brain, especially with cerebrospinal syphilis, rarely with multiple sclerosis, if Echinococcus of the brain and toxoplasmosis. Cysticercosis muscles occurs much less frequently and, as cysticercosis subcutaneous tissue and skin, prevents severe clinical picture even when intensity of infection.
Neobyzantine live parasites may not be recognized radiographically. Calcified tsistitserki give a typical picture. They are identified as intensive sharply kontoritehnika shadows, located on clinico muscle fibers. Young tsistitserki oblong, and the old ones more rounded. The size of shadows - from 0,5 to 1,5 cm in diameter. Differential diagnostics can be performed only with calcified by Trichinella, the value of which barely reaches 1-2 mm; calcified Trichinella on the x-ray revealed in the form of multiple point shadows.
The clinical picture of cysticercosis depends primarily on the number and localization of parasites, their degree of development, the peculiarities of the organism.
Cysticercosis eyes usually leads to the disorders of view, leading to blindness. Cysticercosis brain regardless of the location of the parasite occurs the instability of clinical symptoms dominated phenomena irritation affected cysticercosis departments on the phenomena of loss of their functions (see brain, parasites).
Treatment of cysticercosis eyes and brain surgery; for a single tsistitserki and immediate availability of it now. Certainly shown surgical removal of tsistitserki of the fourth ventricle and in General the posterior cranial pits due to their danger to the life of the patient. When multiple cysticercosis brain shown antibiotics (especially streptomycin) in combination with dehydrating means. Applied also steroid hormones, hloridin, anticonvulsants, and other symptoms.
In addition to personal and social prevention cysticercosis and in need of treatment all patients tenisom intestine (see Tenedos).
