Abstract:
Objective To explore the mixed mucinous breast carcinomas(MMBC)and pure mucinous breast carcinomas(PMBC) imaging features,and evaluate the diagnostic value of ultrasound,X-ray and MRI for mucinous breast carcinoma(MBC).Methods Totally 48 cases of MBC proved by postoperative pathology were analyzed retrospectively.Manifestations of ultrasonography,X-ray and MRI of MMBC and PMBC were summarized,and diagnostic values of three methods were compared.Results Most PMBC showed regular shaped (round,oval or lobulated)mass with clear edge,but most MMBC showed irregular shaped mass with unclear edge in three imaging examinations.On sonogram,MBC mainly showed mixed cystic-solid echo,most PMBC showed low blood signal with rear echo enhancement,and most MMBC showed rich blood signal with various rear echo.On MRI,MBC usually demonstrated high or strongly high signal intensity on T2 WI.On DCE-MRI,PMBC was mainly characterized by rim enhancement with persistent enhancement pattern, and MMBC was exhibited more heterogeneous or rim enhancement with plateau enhancement pattern.Three imaging methods were no significant difference in the accuracy of diagnosis between PMBC and MMBC.There was no statistical significance in three imaging methods.Conclusion PMBC and MMBC with different the appearances of ultrasonography,X-ray and MRI have some characteristics.Fully aware of imaging features can not only identify two types of MBC,but also reduce missed diagnosis and misdiagnosis of MBC.
