Rosai-dorfman disease mimicking meningioma

A 65-year-old woman, harbouring Rosai-Dorfman disease confirmed by biopsy of orbital lesion, presented with a history of headaches. Cerebral computed tomography and magnetic resonance imaging revealed an enhancing left temporal convexity lesion mimicking meningioma, however histological examination was diagnostic of Rosai-Dorfman disease. Rosai-Dorfman disease confined to the intracranial is rare. Only 57 cases have been published. Optimal treatment has not been established but complete surgical resection alone seems effective and allows for histological distinction from meningioma
