| 目的 观察罗萨伊-多尔夫曼病（RDD）18F-FDG PET/CT表现。方法 纳入6例活检病理确诊RDD患者，分析其18F-FDG PET/CT及其他常规影像学检查资料，观察RDD 18F-FDG PET/CT表现特点。结果 本组6例RDD中，1例为皮肤原发病变，3例为淋巴结内+结外病变，2例仅有淋巴结内病变；最常见的结外受累部位为骨（n=3），其次为鼻咽/鼻腔及鼻窦（n=2）；PET/CT示其均呈FDG高摄取，最大标准摄取值为4.3~16.5。结论 RDD病灶18F-FDG PET/CT表现为FDG高摄取。 |

| Objective To observe 18F-FDG PET/CT manifestations of Rosai-Dorfman disease (RDD). Methods Six patients with RDD confirmed with biopsy pathology were enrolled, 18F-FDG PET/CT and other conventional imaging data were analyzed, and 18F-FDG PET/CT features of RDD were observed. Results Among 6 RDD patients, primary skin lesion was detected in 1 case, intranodal+extranodal lesions were found in 3 cases, while only intranodal lesion was noticed in 2 cases. The most common extranodal involvements were in bone (n=3), followed by nasopharynx/nasal cavity and sinuses (n=2). RDD presented as high FDG uptake on PET/CT imaging, with the maximum standard uptake value of 4.3-16.5. Conclusion RDD lesions present as high FDG uptake on 18F-FDG PET/CT imaging. |
