PDFAbstract
Objective To explore the MRI features of posterior reversible encephalopathy syndrome (PRES). Methods The clinical material and MRI data of 15 PRES patients were analyzed retrospectively. All the patients were examined by MRI, 4 with MRV examination at the same time, and 3 received contrast enhanced MR scan, 8 with systematic treatment were reviewed by MRI. Results The lesions mainly located in the white matter of bilateral parieto-occipital lobes, followed by frontal lobe, temporal lobe, cerebellum, basal ganglia, callosum and cerebral ganglia. The lesions on MRI appeared as hypointensity or isointensity on T1WI and hyperintense on T2WI, obvious hyperintense on T2Flair, hyperintense or isointensity on DWI mostly, hyperintense on ADC mostly. No obviously abnormal contrast enhancement was found on MRI imagings of patients received contrast enhanced MR scan. 8 received MRI scan 9-12 days after treatment, all the lesions on imagings resolved mostly. Conclusion The MRI findings of PRES have some characteristics. DWI and MRV are helpful to differential diagnosis. And It will be helpful for prognosis if we can made the diagnosis in time.
