What is a Hydatid Cyst (Dog Cyst)?
A dog cyst, also known as a hydatid cyst, is caused by the parasite Echinococcus granulosus. This parasite typically spreads to humans through the feces of dogs and cats. Once it enters the human body, it forms cysts in the liver and other organs, leading to serious health issues. The liver is the most common organ affected by hydatid cysts.
Hydatid Cyst Life Cycle
Hydatid cysts spread to humans when the eggs, found in the feces of infected animals, are ingested. These eggs hatch in the small intestine, and the larvae migrate to organs such as the liver or lungs, where they form cysts. These cysts grow into fluid-filled sacs that can press against surrounding tissues, causing damage and symptoms.
