我们遇到了一个中年无发热的免疫功能正常的妇女轻微咳嗽。正电子发射断层扫描（PET）/计算机断层扫描（CT）显示左上叶广泛实变，无空洞病变、小结节或支气管扩张，显示氟脱氧葡萄糖（FDG）摄取阳性，最大标准摄取值（SUVmax）为26.9。经皮肺穿刺活检标本显示干酪样肉芽肿，无非典型细胞，左胸腔积液培养禽分枝杆菌，活检后发展。在联合化疗约2年后，实变显著减少。临床医生应该记住，肺M。禽流感感染可导致大面积实变，而无其他典型的放射学表现。
We encountered a middle-aged afebrile immunocompetent woman with a slight cough. Positron emission tomography (PET)/computed tomography (CT) revealed a broad left upper-lobe consolidation without cavity lesions, small nodules, or bronchiectasis showing a positive fluorodeoxyglucose (FDG) uptake with a maximum standardized uptake value (SUVmax) of 26.9. Percutaneous needle lung biopsy specimens showed caseous granulomas without atypical cells and Mycobacterium avium was cultured from left pleural effusion, which developed after the biopsy. The consolidation significantly decreased following combination chemotherapy for approximately 2 years. Clinicians should remember that pulmonary M. avium infection could result in a large consolidation without other typical radiological findings.
