There are several reports describing [18F] fluorodeoxyglucose positron emission tomography (FDG-PET) findings in patients with lymphomatoid granulomatosis (LYG). We report a case of grade I LYG that showed increased uptake of FDG. The patient was a 63-year-old Japanese male who underwent an FDG-PET/computed tomography (CT) scan in screening for a malignant lesion. Increased uptake of FDG [maximum standard uptake value (SUV(max)), 3.7] was observed in the right hilar region in FDG-PET and enhanced CT revealed a round, abnormal mass that also showed increased FDG uptake. The patient had no previous symptoms. A tumor biopsy was performed and the histological diagnosis was grade I LYG. Therefore, increased SUV(max) in FDG-PET might be useful for diagnosing of LYG.
有几份报告描述了淋巴瘤样肉芽肿病（LYG）患者的[18F]氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）结果。我们报告了一例I级LYG病例，该病例显示FDG摄取增加。患者为一名63岁的日本男性，在筛查恶性病变时接受了FDG-PET/计算机断层扫描（CT）。FDG-PET显示右肺门区域FDG摄取增加[最大标准摄取值（SUV(max)），3.7]，增强CT显示一个圆形异常肿块，也显示FDG摄取增加。该患者既往无任何症状。进行了肿瘤活检，组织学诊断为I级LYG。因此，FDG-PET中SUV(max)增加可能有助于LYG的诊断。
