Here we present a case of primary intraosseous meningioma with diffuse and symmetrical invasion of skull and scalp, which was preoperatively diagnosed as fibrous dysplasia. We described the clinical and radiological characteristics, discussed the potential pathogenesis of the diffuse lesion, and presented surgical management.展开更多
