【摘要】：目的分析头颈部淋巴结外Rosai-Dorfman病(RDD)的影像学表现。方法回顾性分析7例经病理证实的头颈部淋巴结外RDD的影像学资料。结果 7例患者中,发生于眼眶3例,颅内2例,颅外1例,鼻腔1例。7例中除1例眼眶RDD伴颈部淋巴结肿大外,余6例均为单纯淋巴结外病变。3例眼眶病变表现为眼眶浸润性肿块,伴或不伴邻近骨质破坏;2例颅内病变发生于硬脑膜,T2WI呈明显低信号;1例颅外病变表现为帽状腱膜下软组织肿块,侵袭颅骨向颅内生长;1例鼻腔病变患者表现为鼻腔均质肿块。结论头颈部淋巴结外RDD在不同部位可有不同的影像学表现,不具特征性。当发现颅内硬脑膜肿块、T2WI呈明显低信号、眼眶浸润性肿块以及鼻腔内占位时应考虑到RDD的可能。
[Abstract]:Objective to analyze the imaging findings of Rosai-Dorfman 's disease outside the lymph nodes of head and neck.Methods the imaging data of 7 cases with pathologically proved RDD of the head and neck lymph nodes were retrospectively analyzed.Results among 7 cases, 3 cases occurred in orbit, 2 cases in intracranial, 1 case in extracranial cavity, and 7 cases in nasal cavity, except 1 case of orbital RDD with cervical lymph node enlargement.The other 6 cases were simple extralymph node lesions. 3 cases of orbital lesions showed orbital infiltrating masses.Two cases of intracranial lesions with or without adjacent bony destruction occurred on T2WI of dura mater. One case showed a soft tissue mass under capsid aponeurosis, and one case showed a homogeneous mass of nasal cavity.Conclusion RDD has different imaging features in different parts of head and neck lymph nodes, and it is not characteristic.The possibility of RDD should be taken into account when the intracranial dural masses were found to be hypointensity on T _ 2WI, orbital infiltrating masses and nasal space occupying.
