Echinococcus granulosus is a parasitic tapeworm that can induce hydatid cyst lung. Although the liver is the primary organ affected by this parasite illness, cyst formation is the second most frequently found in the lungs. Dogs are the parasite’s final hosts, whereas sheep or other animals serve as intermediate hosts. Humans are unintentional hosts when contaminated food or water contains the parasite’s eggs. The eggs hatch once inside the human body, and the larvae go to different organs, such as the lungs, where they grow into cysts filled with fluid. The cysts may develop over time and range in size, which increases the risk of consequences including rupture or recurrent infections. A Pulmonary hydatid cyst can go asymptomatic for years, gradually expanding and eventually causing serious health problems if left untreated.<\/p>\n
