摘　　要：目的:分析临床不能扪及的乳腺导管原位癌(DCIS)及其早期浸润的X线征象。方法:经手术、病理证实的乳腺导管原位癌16例和原位癌伴早期浸润9例,观察其X线表现,并与病理对照。结果:25例X线表现均为钙化,其中按钙化形态分导管原位癌以碎石样钙化为主(6/16,37.5%),原位癌伴早期浸润以杆状钙化为主(5/9,55.56%);按钙化分布分,导管原位癌以成簇钙化为主(11/16,68.75%),原位癌伴早期浸润以成簇、段样为主(两者均为4/9,44.44%)。结论:DCIS及其早期浸润的X线表现有一定特征,通过乳腺X线检查,可提高DCIS及其早期浸润的检出率。Objective：To analyze the mammographic features of nonpalpable ductal carcinoma in situ（DCIS） of the breast and early infiltration.Methods：A retrospective study was performed to analyze the mammographic features and to correlate the mammographic and pathologic findings in 16 consecutive cases of DCIS and 9 cases of DCIS with early invasion.Results：The mammographic features of 25 cases all were calcifications.In the form of calcification,the rubbly calcification was common to DCIS,the linear calcification was common to DCIS with early invasion;in the distribution of calcification,the cluster-like calcification was common to DCIS,the segment-like calcification was common to DCIS with early invasion.Conclusion：The mammographic findings of DCIS and DCIS with early invasion were characteristic.By the mammography,the examination of DCIS and DCIS with early invasion can be improved.
