Case Discussion

Hydatid disease is a common parasitic disease affecting humans.

Liver is the most common site, followed by lung.

Rupture of cysts can lead to various complications like ascites, pleural effusion, transbiliary, peritoneal seeding.

Transdiaphragmatic involvement of pleural cavity is a rare occurence, which can produce secondary cysts in pleura and mediastinum.

Hematogenous spread to lung may also produce pulmonary cysts.
