Whole-body PET imaging with 18F-fluorodeoxyglucose (FDG) has been shown to be effective in distinguishing benign and malignant pulmonary disease. Mild elevations in FDG uptake with standardized uptake values (SUVs) less than 2.5 have been reported in benign lesions, including pneumonia. We report a case of presumed bacterial pneumonia with markedly elevated FDG uptake in a patient with a concomitant squamous cell carcinoma in the contralateral lung. SUV's were similar for both lesions (4.9 and 5.4). This case demonstrates an inflammatory etiology for false-positive FDG PET imaging in the evaluation of focal pulmonary abnormalities.
使用18F-氟脱氧葡萄糖（FDG）进行的全身PET成像已被证明在区分良性和恶性肺部疾病方面是有效的。据报道，良性病变（包括肺炎）的FDG摄取轻度升高，标准化摄取值（SUVs）小于2.5。我们报告一例疑似细菌性肺炎患者，其对侧肺部伴有鳞状细胞癌，FDG摄取显著升高。两个病变的SUV相似（分别为4.9和5.4）。该病例证明了在局灶性肺部异常评估中，FDG PET成像假阳性的炎症病因。
