Abstract:
A 38 years-old man, who had olfactive schwannoma totally removed, with favorable clinical evolution and no radiological recurrence, suffered from headache and frontal syndrome, seven years after surgery. MRI of the brain showed multiple extra-axial lesions, disseminated, mimicking multiple meningiomas. The surgical strategy consisted in primary removal of the most symptomatic lesion. Histopathological examination after immunohistochemical tests permitted the definitive diagnosis of Rosai-Dorfman disease of the central nervous system. Evolution was still favorable 6 months after surgical removal of the whole lesions.
