Fig. 1.

B-mode sonography of the first tumor in the caudal pole of the right parotid gland (1. case), GP – parotid gland, UK – mandible

Fig. 2.

Virtual Touch Imaging Quantification of the first tumor in the caudal pole of the right parotid gland (1. case). You can see that the region of interest is measured and shows a colour-graded scale. Blue regions depict tissue that is more elastic than red coloured regions

Fig. 5.

Color-coded duplex sonography of the second tumor in the right parotid gland (1. case). It shows a diffusely vascularized pattern with no characteristic pattern and an anechoic area indicating a cystic area

Fig. 6.

Virtual Touch Imaging Quantification of the second tumor with one cystic area (“black area”) and a colour-graded scale in the right parotid gland (1. case). Blue regions depict tissue that is more elastic than red coloured regions. The red areas can be artefacts because of the surrounding bone. One measurement shows the velocity of the shear waves

Tumor mass after resection (1. case): Both entities together: on the left side beige-browny, lobulated cut surface with a cystic formation (pleomorphic adenoma, arrow), on the right side browny-yellow, polycystic cut surface (cystadenolymphoma, asterisk)
