Failure to comply with hygiene after contact with these animals helminth eggs can get into the gastro-intestinal tract of man. In the intestine, the larvae from eggs that penetrate the blood vessels and entered into various organs, turning it into hydatid cyst - Finns. Finn is a bubble of thick, double-walled shell, in which the parasite develops. Finns are found most frequently in the liver and lung at least - in the brain. Over time, the Finns increase in size, begin to compress the surrounding tissue and disrupt the normal functioning of the organs.
