Differential diagnosis of multiple sclerosis and multiple metastatic encephaloma / 肿瘤研究与临床

ABSTRACT

Objective To investigate the diagnostic points of multiple sclerosis and multiple metastatic encephaloma.Methods Choose a case of multiple sclerosis,which had been misdiagnosed as multiple metastatic encephaloma and operated on,to analyse its reasons of misdiagnosis.Results Reasons for the misdiagnosisThe neglect of the importance of the disease history.The scant knowledge of the early represen- tations of the atypical MS(demyelinating pseudotumor).The lack of the knowledge of the non-demyelinating lesions of the MS.The lack of attention to the different representations of the MRI scan between the acute MS and the multiple metastatic encephaloma.The excessive importance is attached to the imageological report. The neglect of the routine examination of cerebrospinal fluid.Conclusion When multiple metastatic en- cephaloma develops,the differential diagnosis of MS should be made.The further examinations should be done to those cases which are hard to tell the difference with metastatic encephaloma by clinical and imageo- logical representations.Try to avoid undergoing surgery or radiotherapy hastily.
