Аннотация
BACKGROUND: This report describes the clinical presentation and management of aruptured giant thoracic hydatid cyst in a young adult, highlighting the diagnostic and therapeuticchallenges associated with pulmonary echinococcosis, particularly in endemic regions. The caseemphasizes the importance of early recognition to prevent severe complications.
METHODS: A 22-year-old college student from Iran presented with progressive dyspnea, chest pain, fever, cough,and hemoptysis. Imaging studies, including chest radiography and computed tomography, wereperformed, revealing a giant cystic lesion in the left hemithorax with the pathognomonic "waterlily" sign. Surgical intervention via posterolateral thoracotomy was undertaken, involvingcomplete aspiration of the cyst, cavity cleansing, and chest tube placement.
RESULTS: Intraoperative findings confirmed a giant ruptured hydatid cyst. The cyst was successfully excised, and the patient received postoperative albendazole therapy to prevent recurrence. Histopathological examination confirmed the diagnosis of Echinococcus granulosus infection. The patient's symptoms resolved following surgery, with no immediate postoperative complications.
CONCLUSION: Ruptured pulmonary hydatid cysts can present with acute respiratory symptoms and characteristic imaging signs such as the "water lily" sign. Surgical removal remains the cornerstone of treatment, complemented by antiparasitic medication. In endemic areas, heightened clinical suspicion and prompt intervention are essential to reduce morbidityand prevent life-threatening hypersensitivity reactions.
