Malignant behaviour of primary intracranial Rosai Dorfman disease: A rare presentation of a benign disease
2021, NeurochirurgieCitation Excerpt :S-100 positivity is consistent with the diagnosis of RDD and Langerhans cell histiocytosis, but allows to exclude Erdehim-Chester disease [23]. Unlike Langerhans cell histiocytosis, histiocytes in RDD typically do not show indented or reniform nuclei, do not contain Birbeck granules [11], and are negative for CD1a, langerhin (CD207) and mutant BRAF (V600E) protein [22]. Treatment of intracranial RDD is controversial and includes surgical resection, medical and radiation therapies [6].
Intracranial Rosai-Dorfman Disease Involving the Cavernous Sinus: A Case Report and Review of the Literature
2018, World NeurosurgeryCitation Excerpt :The immunohistochemical findings will be immunoreactive for S-100 protein, CD68 antigen, and vimentin but negative for CD1a, CD15, and CD30, without cellular atypia and mitosis. These findings make it difficult to differentiate from meningioma, Langerhans cell histiocytosis or histiocytosis X, lymphoproliferative disorders, plasma cell granulomas, Hodgkin's lymphoma, and infectious processes in the CNS.6,8,9,19,27,29,32 Although some hypotheses have been proposed, the etiology of RDD remains unclear.
Rosai-Dorfman Disease Presenting as Peripheral Vascular Insufficiency
2018, Annals of Vascular SurgeryIntracranial Rosai–Dorfman disease
2016, Journal of Clinical NeuroscienceCitation Excerpt :T1-weighted MRI showed that the intracranial RDD was usually an isointense or hyperintense mass with distinct borders, and had avid homogenous contrast enhancement. On T2-weighted scanning, the lesions usually presented as isointense [19]. Moreover, an exceptional case was also reported where the lesion could be isointense on T1-weighted but hyperintense on T2-weighted MRI with minimal contrast enhancement [8].
Radiology-pathology case report: Isolated extranodal Rosai-Dorfman disease of the skull base
2013, Clinical ImagingCitation Excerpt :In a recent series of head and neck RD, exclusive extranodal disease occurred in 38% (5/13) of patients, dural based lesions in exclusive extranodal disease occurred in 15% (2/13) of patients, and primary lytic bone lesions occurred in only 8% (1/13) [4]. On imaging, CNS RD most commonly resembles a meningioma and definite differentiation is often not possible [3,5,6]. Radiologic and nuclear imaging can add some diagnostic value between these two entities, however.
