Imaging of Benign Neoplastic and Nonneoplastic Salivary Gland Tumors.

This article reviews the multimodality diagnostic imaging features of benign neoplastic and nonneoplastic tumors associated with the major salivary glands. Examples of neoplastic conditions that are depicted and discussed include pleomorphic adenoma, Warthin tumor, oncocytoma, peripheral nerve sheath tumors, lipoma, and hemangiomas or hemangioendotheliomas. Examples of nonneoplastic conditions that are depicted and discussed include ranulas, benign lymphoepithelial lesions, Kimura disease, and vascular malformations. Specific imaging and clinical features of these conditions are emphasized in this article.
