Positron emission tomography (PET) has come to play an increasingly important role in the evaluation of lung cancer patients, both for diagnostic staging and post-treatment follow-up. As is true for other techniques, PET gives false positive and negative results. False positives have been described in the presence of certain active infections and inflammatory lesions, such as tuberculous granulomas, coccidioidomycosis, aspergillosis and histoplasmosis. We report the case of a man whose PET gave a false positive and in whom both lung cancer and tuberculosis were present. A radical change in therapeutic approach was required, making the case interesting.
正电子发射断层扫描（PET）在肺癌患者的评估中发挥着越来越重要的作用，无论是用于诊断分期还是治疗后随访。与其他技术一样，PET也会出现假阳性和假阴性结果。在某些活动性感染和炎症性病变存在时会出现假阳性，如结核性肉芽肿、球孢子菌病、曲霉菌病和组织胞浆菌病。我们报告了一例PET出现假阳性且同时患有肺癌和肺结核的男性病例。治疗方法需要彻底改变，这使得该病例很有意思。
