Abstract:
Purpose To explore the value of ultrasonography in distinguishing periductal mastitis(PDM)from granulomatous lobular mastitis(GLM)and summarize the sonographic features of non-puerperal mastitis(NPM).Materials and Methods The ultrasonographic findings of 134 NPM(84 PDM,50 GLM)patients treated in the Second Hospital of Lanzhou University from July 2016 to June 2021 were retrospectively analyzed.Comparing PDM and GLM sonograms,the difference of lesion number,lesion side,lesion orientation,distance from the nipple,long diameter,thick diameter,aspect ratio,boundary,edge,edge,shape,internal echo,peripheral high echo halo,rear echo,calcification,internal blood flow,ipsilateral axillary lymph node enlargement,and summarize the characteristics of NPM according to the lesion morphology and internal echo.Results There was no statistical difference between PDM and GLM(P＞0.05).But the probability of PDM combined with ipsilateral axillary lymph node enlargement was slightly higher than that of GLM(x2=4.209,P=0.040).The ultrasonography of 134 cases of NPM lesions was divided into 7 types according to the morphology and echo changes.The abscess type was more common in GLM than in PDM(x2=4.928,P=0.026).Conclusion There is no significant difference between PDM and GLM.In the case that PDM and GLM cannot be distinguished clinically and radiologically,it is recommended to perform puncture biopsy to determine the pathological type before treatment,which may be more conducive to obtaining the best prognosis for patients.In addition,the classification of NPM into 7 types is helpful for sonographers to grasp the ultrasonographic characteristics of NPM to diagnose NPM early.
