Isolated intracranial Rosai-Dorfman disease (RDD) is extremely rare in pediatric patients. We present the case of a 22-month-old boy whom had isolated intracranial RDD involvement. To our knowledge, a parieto-occipital regional involvement without a dural tail sign has not been previously documented. Also, the mass contained hyperintense central T1 foci, and hypointense T2 and gradient echo foci; which are helpful in the differential diagnosis from meningioma. The magnetic resonance and computed tomography imaging findings are discussed and the follow-up course is presented in this paper.
孤立性颅内Rosai-Dorfman病（RDD）在儿科患者中极为罕见。我们报告了一例22个月大的男孩，其患有孤立性颅内RDD累及。据我们所知，此前尚未有关于顶枕区受累且无硬膜尾征的记录。此外，该肿块包含T1加权像高信号的中央灶以及T2加权像和梯度回波序列低信号灶；这些表现有助于与脑膜瘤进行鉴别诊断。本文讨论了磁共振成像和计算机断层扫描成像结果，并介绍了随访过程。
