A Giant Pulmonary Hydatid Cyst in a 13-Year-Old Child: A Case Report

: Hydatid disease has been introduced as a crucial health issue in the Eastern Mediterranean by the World Health Organization. Surgery is the standard gold treatment for hydatid disease. Here, we reported a case of a large hydatid cyst involving the lung in a 13-year-old girl complaining of shortness of breath and cough for 8 months. Early symptoms include fever, cough, and shortness of breath. After admission, computed tomography verified giant lung hydatid cysts. Complete collapse of the right lung and progressive respiratory distress of the patient were treated with thoracotomy considering the size of the hydatid cyst in the lung. It should be noted that in such patients, the preservation of lung tissue function is very significant, and also, the less part of the lung is removed after surgery, the fewer complications the patient will suffer.
