[Intracranial location of a case of sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) mimicking meningioma].

Sinus histiocytosis with massive lymphadenopathy was first described in 1969 in lymphnodes by Rosai and Dorfman ad subsequently in other organs including skin, bone ad soft tissue. Extranodal involvement has also been recognised, but central nervous system manifestations are extremely rare and clinical and radiological findings are suggestive of meningioma. We report a meningeal nodule in a young woman, clinically diagnosed as possible meningioma. A review of literature of previously reported intracranial lesions is presented.
