[Abstract]Objectie：To explore the features of mas-likeinvasivebreastcancer（IBC-ML）withone lesionand without skin invasion，lymph nodesordistant metastasisandfibroadenoma（FA）.Methods：Thedataof39casesofIBC-ML whounderwent enhanced MRIexaminationinNantong Traditional Chinese Medicine Hospital from January2016toJune2O2 werecollcted. All ofthem wereconfirmedbypathologic.Tedataof31casesofFAduringthesameperiodwerecolected，allofthemonly hadonelesionandwereconfirmedbypathologictooThediferences inmorphology，MRIsignalcharacteristics，thetypeof timeintensitycurve（TIC）andotherfeatureswerecomparedbetweenthetwogroups.Results：Therewasnostatisticalysignificantdifernceinthelocation，distributionquadrant，presenceorabsenceofcapsule，cystictransformationornecrosis，the signal characteristics of T2 weighted imaging（T 2 WI） and diffusion weighted imaging（DWI） between the lesions of two groups（all P>0.05 ）.Therewerestatisticallysignificantdiferenes inthe shape，boundary，presenceofburrs，calcification，thickeningof thesupplyingarteries，thesignalcharacteristicsofTweightedimaging（TWI），thedegreeofenhancementinthefirstpaseof enhanced scanning，and the type of TIC between the lesions of two groups（all P<0.05 ）.The average maximum diameter of the lesions in IBC-ML waslarger thanthat inFA，theaverage apparent diffusioncoeficient（ADC）valueof IBC-MLwas lower than that in FA（all P<0.05 ）.TheAUCs to diagnose IBC-ML by irregular lesion，unclear boundary，presenceof burs，low signal intensityonTWI，signficantenhancementinthefirstphase，andanon-inflowtypeinTIC，combined withpredictiveprobabilitywere060，0.31，.833，0.639，.867.849，nd0.97，espectivelyConclsion：Theirgularsape，uaro ary，presenceofurrs，andwithsignificantenhancementinthefistphaseofenhancedscan，aswellasanon-inflowtypein
