Abstract：Objective To discuss the ultrasonographic features of mucinous carcinoma of breast and to analyse the causes of misdiagnosis of ultrasound.Methods The ultrasound imaging and clinical data of 15 patients were retrospectively analyzed,who were diagnosed as mucinous carcinoma of breast by pathology.Results The ultrasound misdiagnosis rate of this group was 80％.Among them,the 8 cases were diagnosed as benign nodules by ultrasound,4 cases were diagnosed as mammary gland fibroma,only 3 cases were diagnosed as mucinous carcinoma of breast.Ultrasound images showed that morphological rules accounted for 93.3％ and clear boundary accounted for 73.3％.93.3％ (14/15) of the mass was with posterior echo enhancement.60％ (9/15) was hypoechoic.40％ (6/15) was equal echo.46.7％ (7/15) of the mass echo uniform.Internal distribution was uneven strip for 53.3％ (8/15) mass.The liquid region within 26.7％ (4/15) mass was seen.There was no significant increase in the axillary lymph nodes.Within 13.3％ (2/15) of lesions,artery resistance index was over 0.8.Conclusion The general ultrasound breast mucinous carcinoma has a certain characteristic performance,but was easily diagnosed as benign fibroma by mistakenly.Careful observation and identification is needed.
