BACKGROUND: Diagnosis of @entity189 can be difficult due to its benign appearance on mammograms and ultrasonographic (US) images. In the light of the rather scarce literature, core needle biopsy (CNB) has proved useful in diagnosing @entity75 . PURPOSE: To assess mammographic, US, and CNB findings of mucinous @entity0 and to correlate them with final histology obtained in therapeutic surgery. MATERIAL AND METHODS: From 2000-2006, 25 @entity189 detected with CNB were surgically removed. The mammography, US, and CNB results were analyzed and correlated with final histology. RESULTS: Ninety-six percent of the @entity189 (24/25) were visible with US. All except two of the 24 @entity5 were solid masses. All the mixed-type lesions (group 2) were hypoechoic and had irregular or lobulated margins and heterogeous internal echotexture. The US features were more variable among the 14 pure @entity189 (group 1) and the six US visible @entity189 with @entity5 cells outside the @entity5 (group 3). Fifty-seven percent of group 1 and 50% of group 3 @entity5 had clearly lobulated or irregular margins. Fifty-seven percent of group 1 and 67% of group 3 @entity5 were hypoechoic. A vast majority of these @entity5 had heterogenous echotexture. Seventy-one percent (17/24) of the lesions visible with US had posterior acoustic enhancement. Eighty percent (20/25) of the @entity189 were classified as BI-RADS 4 lesions in US. All the lesions with images available were visible on mammograms, where most of the @entity5 were seen as a high-density circumscribed lesion and classified as BI-RADS 4 lesions, while none were classified as BI-RADS 1, 2 or 5. The sensitivity and positive predictive value of @entity189 was 100%. CONCLUSION: CNB was found to be a highly reliable diagnostic tool for diagnosing @entity189 in this selected material. US findings of pure @entity189 were variable, however, all reached BI-RADS 4 category. The presence of posterior acoustic enhancement beneath a solid breast lesion should raise suspicion of @entity189 . Most of the @entity5 appeared as BI-RADS 4 lesions in US and in mammography thus making both a useful tool for raising a suspicion of @entity5 .
