What condition results if Taenia larvae develop into cysts in non-intestinal tissues like the liver or brain?
Answer
Cystic echinococcosis or hydatid disease.
Tapeworms, specifically *Taenia solium* (pork tapeworm) and *Taenia saginata* (beef tapeworm), reside in the digestive tract as adults after ingestion of contaminated meat. However, the infection carries a serious systemic risk if the ingested larval stage develops incorrectly, forming cysts in tissues outside the alimentary canal, such as the liver, lungs, or brain. This severe condition where larvae form tissue cysts is specifically termed cystic echinococcosis, also referred to as hydatid disease, often requiring surgical removal of the cysts.
