male, 66 year(s)
 
 
  • Figure 1
    A sonograph of skin tumor

    A transverse gray-scale high frequency sonography scan of the skin showing a hypoechoic tumor with well-defined lower and lateral margins. The tumor measured 3.55 mm in thickness.

     
    Area of Interest: unknown; Imaging Technique: sonography of skin tomur;
     
     
  • Figure 2
    Color-Doppler revealing skin tumor

    A color-Doppler sonography scan revealing intratumor vessels.

     
    Area of Interest: unknown; Imaging Technique: color Doppler skin tumor;
     
     
  • Figure 3
    Enhanced color-Doppler with intravenous contrast agent

    A color-Doppler sonography scan after injection of 2.5 ml of an intravenous contrast agent showing an enhancement of the intratumor vessels.

     
    Area of Interest: unknown; Imaging Technique: Enhanced color Doppler with intravenous contrast agent;
     
     
  • Figure 4
    US Doppler spectrum

    The arterial flow spectrum showing a low resistive index of 0.53.

     
    Area of Interest: unknown; Imaging Technique: US Doppler spectrum;

    Throacic CT

    A contrast enhanced thoracic CT showing a subpleural metastasis in the right hemithorax which is less than 0.5 cm (indicated by an arrow).
