Fig. 2

(case 2 and 3) a Left breast ultrasound image shows a well circumscribed, lobulated, predominantly hypoechoic, wider than taller lesion with internal anechoic cystic spaces and mild posterior acoustic enhancement. b Colour Doppler image shows internal vascularity within the lesion. c Axial T1W MR image of the left breast shows a large, well circumscribed heterogeneous signal intensity mass lesion occupying the entire breast with multiple hyperintense clefts and cystic spaces. No pectoralis muscle invasion seen (red arrow). d Axial DCE MR image of left breast shows heterogeneous intense enhancement of the mass lesion with non-enhancing clefts and cystic spaces. e DWI image shows patchy areas of focal hyperintensity in solid components. f Corresponding ADC map shows focal mild hypointensity (area of true restricted diffusion). g, h US image of right breast shows a well circumscribed hypo to hyperechoic lobulated mass lesion with focal microlobulations (red arrow), areas of posterior acoustic shadowing (red asterisk), internal echogenic septae (yellow arrows) and few small hypoechoic cystic spaces (white arrow)
