Abstract:
Objective To summarize the clinical and imaging characteristics of primary Rosai-Dorfman disease (RDD)in central nervous system in order to understand well its features and improve the diagnosis.Methods The clinical and imaging features in 3 patients with RDD in CNS proved by pathology were retrospectively analyzed in combination with the related literatures.Results The lesions in 2 patients occurred in brain and other lesion in 1 occurred outside the brain.Iso-or slight hyperintensity on T1 WI and marked enhancement of the lesion were found.Single lesion was found in 2 patients near the dura mater and located near the superior sagittal sinus or cervical spinal cord.Multiple lesions in 1 patient were located in the lateral ventricle.Conclusion It’s suggested that single or multiple lesions in dural or spinal meninges located in the midline or near the intracephalic venous system would be considered as RDD in CNS.
