摘要

罗赛-多夫曼病(RDD)是一种不常见的组织细胞疾病,好发于结节和/或结节外部位。结节外 RDD 的临床和放射学表现多种多样,经常导致误诊。胃肠道(GI)系统受累的病例并不多见,仅占报告病例的不到1%。在此,我们介绍了一例 54 岁男性患者的病例,他主诉腹胀,被诊断为影响乙状结肠的 RDD,表现为乙状结肠肿块。患者既往曾因肝细胞癌(HC)接受过肝移植手术。本报告详细介绍了多相位对比增强计算机断层扫描(CT)和氟脱氧葡萄糖(18F-FDG)正电子发射计算机断层扫描(PET-CT)对累及乙状结肠且无淋巴结病的 RDD 的成像结果,并对相关文献进行了综述。

Case report: A rare case of isolated sigmoid Rosai-Dorfman disease on contrast-enhanced CT and 18F-FDG PET/CT
Rosai-Dorfman disease (RDD) is an uncommon histiocytic disorder that occurs in nodal and/or extranodal sites. Extranodal RDD exhibits a wide range of clinical and radiological presentations, frequently leading to misdiagnoses. Involvement of the gastrointestinal (GI) system is uncommon, accounting for less than 1% of the reported cases. Here we present a case of a 54-year-old male who complained of abdominal distention and was diagnosed with RDD affecting the sigmoid colon, manifesting as a sigmoid mass. The patient had a past medical history of liver transplantation due to hepatocellular carcinoma (HC). This report details the multiphase contrast-enhanced computed tomography (CT) and fluorodeoxyglucose (18F-FDG) positron emission tomography (PET-CT) imaging findings of RDD involving the sigmoid colon without lymphadenopathy, and a review of the relevant literature is provided.
