A patient, diagnosed with two hydatid cysts in the right lung via thoracic computed tomography (CT) at a healthcare facility due to complaints of cough and dyspnea, was initiated on albendazole treatment. Two weeks after starting treatment, the patient presented to our Emergency Department with complaints of general malaise, severe respiratory distress, and chest pain. Following physical examination and radiodiagnostic evaluations, a diagnosis of tension pneumothorax was established, and urgent intrapleural air drainage was performed. After stabilization of the patient’s general condition, elective surgical treatment for the hydatid cyst was undertaken.
