Warthin tumor is the second most frequent benign tumor of the parotid gland. Multifocal Warthin tumors are rarely bilateral synchronous. Six synchronous bilateral cases with more than two nodules of Warthin tumor have been described in the literature; only three cases had 4 or 5 tumor nodules. None of these had also extra-parotid localizations. We report a rare case of a patient with four bilateral synchronous Warthin tumors of parotid glands and we present a complete review of the literature. A 72-year-old woman presented at our division with a 12 months history of bilateral parotid swelling. Magnetic resonance imaging revealed four bilateral nodular lesions of the parotid glands. Fine-needle aspiration biopsy was indicative of Warthin tumors. The patient underwent surgical treatment. Multifocality should be kept in mind when a Warthin tumor is diagnosed. Therefore, magnetic resonance imaging represent an important tool in the diagnostic algorithm, and an adequate follow-up is mandatory.
