Primary pleuropulmonary echinococcosis - Varied manifestations

Echinococcosis commonly known as “hydatid disease” is seen worldwide and is caused by eccinococcus larvae. It mainly affects liver (70%) followed by lung involvement (20%) in adults. In the thoracic cavity, it mostly affects lung parenchyma but pleural involvement is well documented. We present three cases of hydatid disease affecting pleuro-pulmonary system as primary site of involvement without hepatic involvement.
