A) Echo Color Doppler: Longitudinal scan. Pleomorphic adenoma with prevalent periphery vascularization with few central spots. TYPE 1.

B) Cystic lesion with hypervascularized septum (Color Doppler). TYPE 2. This finding is indicative of Warthin’s cystoadenolymphoma.

C) Hypoechogen neoplasm with intralesion vascularization (Echo Doppler). TYPE 2. Non Hodgkin Lymphoma.

D) Hypoechogen lesion with total parotid alteration (Echo Color Doppler): spread vascularization. TYPE 3-4. Unidifferentiated carcinoma.
