Unusual radiologic manifestations of the echinococcus infection in the thorax

Unusual location and presentation of hydatid cyst disease in the thorax requires careful consideration with respect to clinical approach and therapy. In this pictorial essay, we present imaging findings and describe treatment of thoracic hydatid cysts in patients with lung, mediastinal, chest wall, cardiac, endobronchial, pulmonary artery, and diaphragmatic involvement. A review of the literature is also included.
