Hepatopulmonary hydatidosis in a ten-year-old girl: a case report

Hydatid disease is a parasitic infection caused by the tapeworm Echinococcus granulosus and is characterised by cystic lesions in the liver and lungs. Concomitant pulmonary and hepatic localization of hydatid cysts in childhood is unusual and represents a distinct clinical entity called hepatopulmonary hydatidosis.

A ten-year-old Caucasian girl, a permanent resident of rural Greece, was admitted to hospital reporting a nonspecific symptomatology compatible with a diagnosis of viral infection. Chest radiography revealed a large homogenous circular opacity in the right lung field. On the basis of imaging studies, a diagnosis of hydatidosis was made with synchronous hepatic and pulmonary involvement, successfully managed through a single-stage transthoracic surgical approach.

This case report highlights the necessity of realizing that hydatid disease continues to be a public health problem, which often remains asymptomatic for years. Therefore, the presence of any homogeneous cystic spherical opacity on routine chest radiography should raise the suspicion of hydatid disease, mainly in endemic areas such as Greece. General practitioners and physicians involved in pediatric care need to be familiar with the diagnosis and management of the variable clinical manifestations of hydatid disease. Taking into consideration that hepatopulmonary hydatidosis represents a special entity that requires a different therapeutic approach may positively affect its economic and social-related burden.
