Rosai-Dorfman disease (RDD) is a rare benign proliferative disorder. Lymph nodes are the usual and common sites of involvement. Involvement of the extranodal site is also documented in the literature. 18F-fluorodeoxyglucose positron emission tomography computed tomography (F18-FDG PET CT) is a valuable whole-body imaging modality in staging and treatment response of various lymphoproliferative and solid organ malignancy. Similarly, PET CT survey can detect the involved sites of various body systems, infective or inflammatory diseases, and provide guidance for biopsy and to reach to diagnosis. Here, we present a case of RDD, who presented with neurological manifestations and on F18-FDG PET CT, diagnosed with multiorgan involvement.
罗萨伊-多夫曼病（RDD）是一种罕见的良性增生性疾病。淋巴结是常见的受累部位。文献中也记载了结外部位受累的情况。18F-氟脱氧葡萄糖正电子发射断层扫描计算机断层扫描（F18-FDG PET CT）是一种在各种淋巴增殖性疾病和实体器官恶性肿瘤的分期及治疗反应评估中具有重要价值的全身成像方式。同样，PET CT检查可以检测身体各个系统、感染性或炎症性疾病的受累部位，并为活检及诊断提供指导。在此，我们报告一例RDD病例，该患者表现出神经症状，经F18-FDG PET CT检查诊断为多器官受累。
