Background: Isolated intracranial Rosai-Dorfman disease (RDD) is an extremely rare, idiopathic histo-proliferative disorder. RDD is associated with the proliferation of histiocytes and emperipolesis. Case Presentation: we report a case with isolated intracranial RDD. A 47-year- old man presented with a dizziness, falling, and then secondary generalized seizure, hemiparesis and right hemisensory deficit. This case preoperatively was misdiagnosed with meningioma. Histopathological examination revealed pale histiocytes displaying emperipolesis which were positive for S-100 and CD68 proteins and negative for CD1a marker. BRAF V600E mutation was negative. Conclusion: In this case, total resection was performed and clinical symptoms were regressed completely.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
