Multiple complex cysts involving the imaged liver, some of which contain fat, calcifications, and daughter cysts. Bulky complex cystic structures in the right pleural space compressing the lung parenchyma. Few small mediastinal cysts.

Case Discussion

Classic imaging features of hydatid disease with a combination of daughter cysts, partially calcified cysts, and cysts containing dots of fat (indicating communication with the biliary tree) in the liver, which is the most common site of disease. The liver disease has presumably extended through the diaphragm and dissected along the pleural space, resulting in compression of the lung parenchyma. Pleural disease is not common compared to the involvement of the lung parenchyma directly.
