Abstract:
Objective To analyze MRI manifestation of the neonatal purulent meningitis retrospectively,including conventional MRI and diffusion-weighted imaging (DWI),and to evaluate the value of MRI in early assessment of the neonatal purulent meningitis.Methods From Jul 2004 to Jul 2009,20 full-term newborns (14 male,6 female) from Shengjing hospital were included in this study,all of which were diagnosed as purulent meningitis.MRI and DWI examinations were performed within 72h after the diagnosis.Results (1) Among those 20 infants,19 infants (95%) had positive findings,including 7 cases of cerebral infarction,4 cases of subdural effusion,3 cases of encephalomalacia,1 case of hydrocephalus,1 case of ependymitis and 7 cases of intracranial hemorrhage.(2) Among the 7 cases of infarction,5 cases showed hypointensity on T1WI and hyperintensity on DWI and T2WI,but the other 2 cases only showed hyperintensity on DWI.Conclusion MRI can detect infarction and hemorrhage in the early stage of purulent meningitis.So MRI,especially DWI,is very important for the early diagnosis and evaluation of neonatal purulent meningitis.
