Lung and Parietal Hydatid Disease

Hydatid disease, which is also known as cystic echinococcosis, is a zoonotic infection caused by the cestode tapeworm Echinococcus granulosus and rarely by Echinococcus multilocularis. In this report we describe an unusual case of a 75-year-old man who was admitted to our hospital for a mass extending from the lumbar region to the right cervical region. Computed tomography and MRI revealed a huge cervical and thoracic mass of the right chest made of multiple cystic lesions. The patient was put on medical treatment. The diagnosis, clinical features, treatment, and prevention in this case of multi-organ echinococcosis are discussed, in light of the relevant literature.
