Parenchyma Preserving Surgery in Giant Hydatid Cyst of Lung: A Case Report

Cystic echinococcosis (CE) is parasitic infestation characterized by the development of cyst as a consequence of the parasitization of humans by the larval stages of cestode Echinococcus granulosus. We present a case of 66 years old man who presented with a history of dry cough, mild fever and occasional shortness of breath for 1 year, which was gradually progressive with no history of chest pain or weight loss. Chest x-ray revealed a well-circumscribed homogenous opacity in the right hemithorax. Computed tomography (CT) of the chest revealed a large cystic lesion 18× 15 × 14 cm in the right hemithorax involving the whole of the right lower lobe and causing compression atelectasis of the middle lobe. The patient underwent lung preserving surgery with cystectomy and capotionnage. The patient was discharged on the 6th postoperative with a good clinical and radiological outcome. This case report highlights that lung-preserving surgery can be performed in giant hydatid cysts with a good outcome.
