Overview
Persons with echinococcosis often remain asymptomatic. The clinical presentation of echinococcosis infection depends upon the site of the cysts and their size. The cysts are mainly found in the liver and lungs but can also appear in the brain, eyes, spleen, kidneys, heart, bone, and central nervous system. Cyst rupture is most frequently caused by trauma and may cause mild to severe anaphylactic reactions, even death, as a result of the release of cystic fluid.[1]
