Human hydatid disease is mainly caused by infection with the larval stage of dog tapeworm Echinococcus
granulosus. The disease is widely endemic in many sheep and cattle rearing locales such as
Australia, Latin America, Africa and Middle Eastern countries, and now worldwide. Hydatidosis is a
serious pathogenic, zoonotic and parasitic infection of humans, following ingestion of tapeworm eggs
excreted in the feces of infected dogs. Children of all age groups are susceptible from pet dogs (Urban
area) or stray dogs (Rural area) and localization of the disease in the lungs is more commonly seen.
Multiple liver cysts in the pediatric age group were relatively uncommon. Surgery remains the primary
treatment and the only hope for complete cure. PAIR is considered an alternative treatment for
cystic echinococcosis (hydatid disease) and is often indicated for patients who do not respond to open
surgery or drugs.
