Cystic echinococcosis (CE) is an important helminthic zoonotic disease that commonly affects the liver and lungs. Imaging methods and serology establish the diagnosis in most cases. Chest x-ray can diagnose uncomplicated pulmonary hydatid cysts, whereas superinfection and/or rupture of the hydatid cyst (complicated cysts) may change the radiographic appearance and lead to delayed diagnosis and treatment. We report the case of a patient with hemoptysis and chest pain, where computer tomography scan of the lung suggested a large, ruptured hydatid cyst. However, serological tests with indirect hemagglutination (IHA)for antibodies were negative, and there was massive growth of in sputum. Based on this, we concluded that the patient had a bacterial lung abscess. The diagnosis of CE was only made after surgical removal of the cyst followed by microscopy and polymerase chain reaction.
囊性棘球蚴病（CE）是一种重要的蠕虫性人畜共患病，通常影响肝脏和肺部。在大多数情况下，影像学方法和血清学可确立诊断。胸部X线可诊断单纯性肺包虫囊肿，而包虫囊肿的继发感染和/或破裂（复杂性囊肿）可能改变影像学表现，导致诊断和治疗延迟。我们报告一例咯血和胸痛患者，其肺部计算机断层扫描显示一个大的破裂包虫囊肿。然而，间接血凝试验（IHA）检测抗体的血清学试验为阴性，痰中出现大量[此处原文缺失具体内容]生长。基于此，我们得出该患者患有细菌性肺脓肿的结论。仅在手术切除囊肿并进行显微镜检查和聚合酶链反应后才确诊为CE。
