Hydatid disease or echinococcosis is a zoonotic parasitic disease.The lung is the second most commonly affected organ after the liver.Intra-thoracic and extrapulmonary hydatid disease is uncommon and may involve the pleura,mediastinum,heart,diaphragm,and chest wall.Unusual locations or complications of thoracic hydatid disease may pose a diagnostic challenge.We present imaging findings of cases with unusual location and presentations of thoracic hydatid disease with emphasis on their clinical implications.
