Patient with Pancoast adenocarcinoma of the lung. Coronal (a) and axial (b) views show soft tissue density (thick arrows) encasing the left carotid artery and subclavian artery (thin arrows). c The tumour is seen as a hypoechoic area, ill-defined on B mode ultrasound with the subclavian artery visible on the periphery (thin arrow). d Simultaneous CEUS clearly defines the hypoenhancing lesion and the previously unseen carotid artery and subclavian artery (thin arrows). e, f Simultaneous B mode ultrasound and CEUS with the biopsy needle (thin arrows) within the hypoenhancing lesion avoiding the critical arterial structures (arrow)
