Parasitic diseases of the brain include cysticercosis and echinococcosis.
Cysticercosis - an infestation of the central nervous system of swine tapeworm larvae. Migration parasite ( oncospheres ) in the body penetrating the gastric mucosa, occurs along the blood vessels in the portal venous system and the systemic circulation. Cysticerci ( Finn ) is a bubble, which has a three-layer structure of wall and filled with a clear liquid . Around the bubble in the brain reactive capsule is formed in the distance - diffuse inflammation dominated toksicheskihvaskulitov. There are single and branched ( ratsemoznye ) cysticerci . The most common sites are the meninges and the superficial layers of the cortex. Less frequent ventricular cysticercosis.
Hydatid disease - damage to the central nervous system of larvae ( Finn ) tapeworm . Migration paths hexacanth tapeworm in humans is the same as that of pig tapeworm . There are two types of tapeworm : twin , or hydatid , and multi-chamber , or alveolar . Echinococcus -chamber wall consists of an inner layer embryonic carrying scolex and outer shell chitin . Cyst filled yellowish liquid containing succinic acid and other components . Dimensions of the parasite are highly variable and can be as large as the big apple . Echinococcus multilocularis is a conglomerate of small bubbles , combined into a single unit of the intermediate connective tissue. Localized mainly in the subcortical white matter of the cerebral hemispheres , at least in the ventricles of the brain. Perifocal brain tissue reaction around the parasite is always pronounced , especially in multicamera echinococci
The clinical picture of parasitic diseases of brain with the clinic tumor.
When cysticercosis you may have headache, nausea , vomiting , epileptiform seizures. Sometimes the mind is disturbed as a hallucinatory states that can suddenly disappear and reappear. Cysticercosis of the ventricles of the brain is accompanied by increased intracranial pressure.
When echinococcosis there are headache, dizziness, vomiting. Paralysis, paresis, mental illness, seizures are possible.
If you suspect a parasitic brain injury you should have a thorough diagnosis, including a study of the cerebrospinal fluid.
