Abstract:
Objective To investigate the imaging features of primary Rosa-i Dorfman disease (RDD)in the central nervous system and to increase the understanding of the disease.Methods The MRI findings of 5 cases with primary RDD of the central nervous system were analyzed retrospectively,and the related literatures were reviewed.Results Four cases located in the cranium,1 case located in the spinal cord,and 5 tumors were attached to the brain (ridge)membrane.The tumor was equal and low signal on T1 WI,and equal or slightly high signal on T2 WI.Obvious enhancement could be seen on enhance study,and obvious enhancementwas visible in adjacent brain (ridge)membrane,in which 1 case involved the skull,with thickening and strengthening of the skull.Tumors were attached to the meninges in a wide range,the local meninges of 3 cases were penetrated by tumor.Conclusion If young and middle-aged males have no obvious specific clinical manifestations,the images of MRI are single or multiple lesions that are closely related to the brain (ridge)membrane in larger extent and easily penetrate the brain (ridge)membrane,the possibility of RDD should be considered.
