RESUMO

Objective ToinvestigatetheMRIandCTimagingcharacteristicsofcerebralpleomorphicxanthoastrocytoma(PXA). Methods CTandMRImanifestationsof5cerebralPXAcasesconfirmedbypathologywereanalyzedandcomparedwiththosecases reportedindocumentation.Results The meanageof5caseswas (27±18)years,andallthecasesrespectivelyhadsinglelesion whichwaslocatedinthecortexorsubcortex.In5cases,3leionsoccurredinthetemporallobe,while1lesioninthefrontallobeand1 lesioninthecerebellarvermis.Solid-cystictumorsin3casesandsolidtumorsin2cases(including1casewithpartialpiamaterinfiltrated) wereidentifiedbyCTandMRI.ThecysticpartoflesionwasshownaslowdensitywhilethesolidpartasmixeddensityonplainCT scan,including1casewithscatteredpoint-stripecalcification.Thesolid-cysticcapsuleandthesolidpartoflesionweredemonstrated asuniform markedenhancementonenhancedCTscan.ThesolidareaoftumorwasshownasslightlyhypointenseonT1WI,slightly hyperintenseonT2WI,markedenhancement,andequisignalorhyperintenseonDWIimage.Thesolid-cysticcapsulewallwasenhanced in3cases,whilethecysticpartwasnotenhanced.ThemildtomoderateedemaaroundthetumorwasdetectedinalltumorsbyCT and MRI.Conclusion PXAoccursmostfrequentlyinthetemporallobeofadolescents.TypicalcharacteristicsofCTandMRIaresolid-cystic massandmarked-enhancementofwallnodule,withdifferentdegreeofedemaaroundthetumor.
