A 60-year-old female patient with a 5-year history of rheumatoid arthritis (RA) presented with pulmonary nodules on chest radiograph and computed tomography (CT) scan. The positron emission tomography (PET) demonstrated mild fluorodeoxyglucose (FDG) uptake in these nodules, which is characteristic of benign lesions. Histopathological correlation confirmed this. Although rheumatoid pulmonary nodules are benign, confirmation to exclude coincidental malignancy is very important. FDG-PET is a noninvasive imaging technique, which acts as a metabolic biopsy and can help in avoiding morbidity and cost of invasive tissue sampling.
一名患有类风湿关节炎（RA）5年的60岁女性患者，胸部X线片和计算机断层扫描（CT）显示有肺结节。正电子发射断层扫描（PET）显示这些结节有轻度氟脱氧葡萄糖（FDG）摄取，这是良性病变的特征。组织病理学相关性证实了这一点。尽管类风湿肺结节是良性的，但排除巧合性恶性肿瘤的确认非常重要。FDG-PET是一种非侵入性成像技术，它起到代谢活检的作用，有助于避免侵入性组织采样的发病率和成本。
