Abstract

With the advent of the Breast Imaging Reporting and Data System (BIRADS), the categorization of the entire gamut of breast lesions has been simplified. However, there are many unusual breast lesions, both benign and malignant, which cannot be categorized accurately using the BIRADS descriptors due to the overlap of features. Carcinomas such as medullary, papillary, and mucinous (colloid) types, may be difficult to recognize as malignant because they may have relatively benign-appearing morphologic features. Well-circumscribed, small, and hyperechoic lesions may not be benign in all cases, and the presence of any microlobulations in margin, vascularity, heterogeneity, round shape, or interval change in size or appearance should raise suspicion of a sinister etiology. Therefore, it is important to be aware of the imaging features of such malignancies so that any mismanagement or undue delay in the diagnosis of any sinister etiology can be avoided.
