female, 51 year(s)
 
 
  • Figure 1
    High frequency US study

    High frequency US scan demonstrates an ovoid hypoechoic tumor with homogeneous echostructure and well-defined lower and lateral margins. The tumor measured: 2.60 mm in thickness (20 MHz) ; 2.72 mm in thickness (13 MHz)

     
    Area of Interest: unknown; Imaging Technique: High frequency US study;
     
     
  • Figure 2
    Color Doppler US study

    Color Doppler sonography scan reveals a tumor containing intratumor vessels. The arterial velocity spectrum shown below the scan was recorded. The resistive index was low : 0.41
