摘　　要：目的探讨乳腺导管原位癌(DCIS)的超声表现特征。方法回顾性分析经病理证实的54例乳腺DCIS的超声表现,包括病灶形态、大小、边缘、边界、内部回声、后方回声、微钙化、导管改变及血供,并与病理结果进行对比。结果54例均经术后病理证实为乳腺DCIS,其中高级别34例,中级别13例,低级别7例;5例伴微浸润灶,均未见腋窝淋巴结转移。声像图表现为片状低回声型20例(20/51,39.22%)、结节状肿块型17例(17/51,33.33%)、导管扩张型8例(8/51,15.69%)、单纯微钙化型6例(6/51,11.76%),3例假阴性,检出率94.44%(51/54)。超声正确诊断44例,准确率81.48%(44/54)。结论乳腺DCIS超声表现具有一定特征性;正确认识其超声征象能有效提高诊断符合率。Objective To explore ultrasonographic features of breast ductal carcinoma in situ （DCIS）. Methods Ultrasonographic images of 54 patients with DCIS were retrospectively reviewed, and the size, shape, margin, boundary, internal echogenicity, posterior acoustic transmission, microcalcifications, ductal changes and blood supply of DCIS were analyzed ＆nd compared with pathological findings. Results All DCIS were confirmed by surgical pathology, including 34 high grade, 13 intermediate grade and 7 low grade lesions. Microinvasion was found in 5 patients, whereas no axillary lymph node metastasis was detected. The ultrasonographic features of DCIS could be classified as sheet hypoechoic type （n= 20, 20/51, 39.22%）, mass type （n=17, 17/51, 33. 33%）, duct dilatation type （n=8, 8/51, 15.69%） and microcalcification type （n= 6, 6/51, 11.76%）. False negative occurred in 3 eases, and the detection rate of ultrasound for DCIS was 94.44% （51/54）. Totally 44 lesions were correctly diagnosed as malignant tumor, and the accuracy was 81.48% （44/54）. Conclusion Ultrasonic manifestations of DCIS have some characteristics, which are helpful to improve diagnostic accuracy.
