Abstract
Parotid gland tumors are almost invariably epithelial tumors such as pleomorphic adenoma. Nonepithelial tumors such as lipoma are rare. According to previous reports, lipomas account for about 1% of all parotid gland tumors. This tumor produces strong signals on Tl and T2 weighted MR images and weak signals on fat suppression images, which confirms the clinical diagnosis.
We report a case of lipoma arising in the parotid gland. The patient was a 53-year-old man. Surgical excision was performed. Sixteen months after the operation, there was no sign of recurrence.
