Figure 5. 34-year-old patient with testicular cancer and pleuropulmonary metastases, which infiltrate the chest wall. (a) On colour Doppler ultrasound mapping vessels were seen in the central region of the tumour. (b) A triphasic high impedant arterial flow pattern was seen suggesting a pulmonary artery (PA) origin. (c) Beneath the PA an additional flow signal (FS) characterized as a monophasic low impedant arterial flow pattern was seen suggesting a central bronchial artery (BA) origin.
