Ultrasound and MR imaging of XXXX .

@entity1 @entity6
AIM: To review the imaging findings of @entity6 , and document the colour flow ultrasound and MR imaging features in this benign condition. MATERIALS AND METHODS: @entity6 was clinically and histologically diagnosed in eight lesions in six @entity1 . All six @entity1 underwent conventional mammography and high frequency grey-scale ultrasound. Colour flow ultrasound was performed additionally in six lesions in four @entity1 and MR imaging in four lesions in three @entity1 before biopsy. The imaging findings were reviewed and correlated with final histological diagnosis. RESULTS: Mammography showed regional asymmetric increased opacity with ill-defined margins in all lesions. A heterogeneously hypoechoic mass with ill-defined margins was identified on high frequency grey-scale ultrasound in all lesions. Marked posterior acoustic shadowing was present in seven of eight (88%) lesions. Six lesions interrogated with colour flow ultrasound showed absence of Doppler signal. MR imaging in three @entity1 revealed non-specific stromal enhancement. CONCLUSION: @entity6 shows absence of Doppler signal on colour flow ultrasound and non-specific stromal enhancement on MR imaging.
