Echinococcosis or hydatid disease is a helminthic infection caused by larvae of tapeworm Echinococcus granulosus. While the cysts can involve all organs, liver is the most common site of infection and the lungs are the second most commonly involved organ in young adults. In addition to endemic areas its incidence is growing all around the world due to the ease of transcontinental travel. Disease presentation varies and usually is due to mass effect or dysfunction of the involved organ and surgical resection is the recommended treatment. Here we present the case of a young man with primary pulmonary echinococcosis with involvement of the entire right lung.
