Ultrasonography demonstrates an irregular shape, parallel orientation, microlobulated margins, heterogeneously hypoechoic mass with posterior enhancement in left breast at 8 to 9 o'clock position in zone two with an area of increased vascularity ( A ). A biopsy needle is seen within the lesion ( B ).

  Fig. 3. The lesion appears hypointense on T1-weighted images ( A ), heterogeneous hyperintense on T2 fat-saturated images ( B ). On dynamic postcontrast evaluation, heterogeneous enhancement of the mass seen with dilated vessel within as well as on the periphery of the lesion. Early ( C ) and delayed postcontrast images ( D ).
