耳下腺部に発生した脂肪腫の1例 A case of lipoma arising in the parotid gland
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.<BR>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.
