A man having 'cyst' in the 'cyst'!

Abstract

Hydatid disease is a zoonotic parasitic infestation caused by tapeworms, particularly Echinococcus granulosus. The lung is the second most site followed by liver accounting for 10%-30% of the cases. Rupture of hydatid cyst can occur into pleura or bronchus. Surgery remains the mainstay of treatment for pulmonary hydatid.
