“…MR imaging is generally accepted as a more sensitive technique than mammography or sonography for the detection of breast cancers. The use of dynamic imaging and pharmacokinetics analysis of dynamic data has increased detection specificity (15,16). In our study, a combined pattern with a mass and non-mass was observed in 6 cases (21%) on MR imaging.…”

Purpose :We performed this study to investigate the characteristic imaging and clinicopathologic features of invasive micropapillary carcinoma of the breast. Materials and Methods:Among the 47 women with surgically confirmed invasive micropapillary carcinoma between 2005 and 2009, 32 patients (mean age, 50 years; range, 37-69 years) had all preoperative mammography, ultrasound (US) and MR images. Two radiologists retrospectively assessed the imaging findings, clinical presentation and histological results of the patients. Results:On mammography, 29 of 32 patients had suspicious findings. Among them, a mass (or focal asymmetry) with calcifications was the most common findings (15/32, 65%). The calcifications were noted in 20 patients (63%) and the shape of calcifications was frequently amorphous or punctate (n = 12, 60%). On US and MR imaging, all lesions had suspicious findings. The most common US findings were single (n = 20) or multiple (n = 10) irregular hypoechoic mass (es). The mass was frequently hypoechoic (n = 29, 97%). On MR imaging, the type of lesions was a mass or masses in 23 (72%), a mass combined with non-mass in six patients, and non-mass lesions in three patients. Histologically, axillary lymph nodes metastasis were very common (25/32, 78%). Asymptomatic clinical presentation was not usual (9/32, 28%). Conclusion:The imaging features of invasive micropapillary carcinomas strongly suggest malignancy. Microcalcifications on mammography, marked hypoechogenicity on US and an irregular mass, often combined with non-mass on MR are common. Axillary lymph node metastasis is commonly associated.
