CT and MRI on tumor like inflammatory demyelinating disease / 临床神经病学杂志

ABSTRACT

Objective To investigate the clinical and imaging characteristics of tumor like inflammatory demyelinating disease of CNS, We have analyzed the reason of misdiagnosis, and summed up the main point of differential diagnosis.Methods We have analyzed 14 cases which were confirmed as demyelinating disease in pathology after the operation, and all the clinical and image data were included.Results CNS inflammatory demyelinating disease could present edema and mass effect by CT or MRI, there was ring potentialization after enhancement, it was difficulty to distinguish from CNS demyelinating disease. All the 14 patients were misdiagnosis as CNS tumor before the operation.Conclusion CNS inflammatory demyelinating disease could have some atypical representation on CT or MRI image, they were made easily the misdiagnosis. We should get the differential diagnosis by many ways including clinical manifestation, course, laboratory examination and imaging characteristics.
