The sialograms of 80 cases with Warthin tumor in parotid gland were analysed. The sialographic characteristics were found as follows: irregular arrangement, dilation and narrow of branch ducts which surrounded the tumor, sausagelike change of main ducts just like that seen in obstructive parotitis, and spot-like dilation of the terminal ducts. The comparative study on roentgen-pathology showed that the spot-like dilation of the terminal ducts was related to the dilation of interlobular duct of the gland surrounding the tumor. The roentgen differential diagnosis of Warthin tumor from the aggressive benign tumor and Sjögren syndrome is discussed.
