Abstract

BACKGROUND AND OBJECTIVES: Ultrasonography represents the initial imaging modality of choice for the assessment of the parotid gland tumors. The aim of this study is to evaluate the role of ultrasonography in differential diagnosis of the parotid gland tumors.
SUBJECTS AND METHOD
Ultrasonography of the 49 patients with parotid gland tumors were retrospectively reviewed. Histology of all cases was confirmed after parotidectomy. The ultrasonographic features of the most common two histologies, namely, pleomorphic adenoma and Warthin's tumor, were compared.
RESULTS
Pleomorphic adenomas were usually solid and they showed lobulation and an exophytic growth. Warthin's tumors usually contained a cystic component, and were usually oval without lobulation and confined to the parenchyma. One of two malignancies showed well-defined margins and five benign tumors showed ill-defined margins.
CONCLUSION
The ultrasonographic features should be cautiously used to discriminate among the various histologies of parotid gland tumors.
