Pulmonary hydatid disease is a common parasitic infection in endemic regions and represents the second most frequent localization of echinococcosis after hepatic involvement. Pulmonary cysts may remain clinically silent for years until rupture or secondary infection occurs. We report the case of an 18‑year‑old male presenting with thoracic pain, dyspnea, cough, and fever. Chest radiography revealed a large cystic opacity within the left hemithorax, while thoracic computed tomography demonstrated characteristic findings of a complicated pulmonary hydatid cyst with bronchial fistulization, including an air‑fluid level and detached floating membranes. This case highlights the major role of imaging, particularly CT, in diagnosing ruptured pulmonary hydatid cysts, evaluating associated complications, and guiding therapeutic management.
