All cases involved both the light leaf and depth leaf, and cervical lymph nodes enlargement could be seen at the affected side. The ADC value of this 5cases is 0.536±0.037, TIC curve of 3 cases shows as B type, and the other 2's showed as C type.The magnetic resonance sialography(MRS) showed normal parotid duct signal intensity.
