PDFAbstract
Objective To analyze the CT and MRI imaging features of posterior reversible encephalopathy syndrome (PRES),in order to improve the diagnostic accuracy of the disease. Methods The clinical material and radiologic data of 15 PRES patients were analyzed retrospectively．The examination included 10 females and 5 males, CT scan(9 patients)and MR scan (1 8 patients), 2 patients were performed CT and MR scan both. Results The occipital and parietal lobes were the most common disease position of the PRES. The imaging findings of RPES presented as low density area on CT image. The lesions were displayed as hypointensity on T1WI and hyperintensity on T2WI and flair images. The location of lesions were parieto-occipital lobes mostly, followed by frontal and temporal lobe, brainstem, cerebellum and basal ganglia. Most 1esions were obviously reduced after treatment except for 1 patient with bleeding. Conclusion The characteristic imaging features could be assessed in patients with PRES. It will be helpful for prognosis if we can made the diagnosis in time.
