The imaging characteristics of invasive micropapillary carcinoma are highly suggestive of malignancy. The lesion is a high-density irregular mass with indistinct margins associated with microcalcifications on mammograms; a solid irregular hypoechoic mass with indistinct margins and frequent axillary nodal involvement on sonograms; and a multifocal mass on MR images. This tumor may necessitate aggressive management

Mucinous carcinoma can be clearly differentiated from other breast tumors on the basis of ADC. The low signal intensity of mucinous carcinoma on diffusion weighted images appears to reflect the presence of mucin and low cellularity. High signal intensity on diffusion-weighted images may reflect the presence of fibrovascular bundles, increased cell density, or a combination of these features
