Abstract:
Objective TosummarizeMRIfeaturesofadultreversiblespleniallesionsyndrome(RESLES)andevaluateitsdiagnosticvalue. Methods ClinicalandMRIdataof15patientswithRESLESwereanalyzedretrospectively.Primarydiseasesandcausesincluded:encephalitis disease,cerebrovasculardiseases,metabolicandelectrolytedisorders.Theclinicalsymptomswereheadache,dizziness,changeofconsciousness, epilepticseizuresandothernonspecificneurologicsymptoms.Thecranialimagingexaminationwasperformedat3.0T/1.5TsuperconductingMR, includingT1WI,T2WI,T2FLAIRandDWI,inwhich7casesunderwentMRIenhancedscanand5casesunderwentMRAexamination.Results Among15patients,MRIfindingsofallpatientswerecharacterizedbythecharacteristic"boomerangsign"ortheovoidabnormalitysignalinthe corporiscallosisplenium,whichwaspresentedascytotoxicedema.Besides,4ofthem werecombinedwithposteriorreversibleencephalopathy syndrome(PRES),whichwascharacterizedbyvasogenicedemainthebilateraloccipital,temporal,parietallobeandcerebellarhemisphere.The clinicalsymptomsofallpatientsimprovedafterreasonabletreatment.Conclusion MRIcharacteristicfindingofadultreversiblesple-niallesionsyndromeisthecytotoxicedemaofthecorpuscallosum,whichcanbeshowedas"boomerangsign"orovalform.Imagingfindingsand clinicalsymptomsarereversible.Thecorrectunderstandingofthisdiseaseisofgreatsignificancetoclinicalrationaldiagnosisandtreatment.
