Hydatid Cyst in the Distal Pulmonary Artery: A Case Report

We report a 21-year-old female with two hydatid cysts localized in the right paracardiac zone and in the left lower lobe. She underwent sequential thoracotomies. Thoracotomy for the right side revealed a hydatid cyst in the pericardial cavity with tight adhesion to the right atrial wall. The second operation confirmed the presence of a distal intrapulmonary arterial hydatid cyst, which was treated with common basal segmentectomy. We report this case because of the rarity of the natural disease and also for choice of method of surgi­cal intervention in such cases.
