Figure 1. Magnetic resonance imaging (MRI) examination revealed a round mass presenting both cystic and solid lesions within the superficial lobe of the left parotid gland. T1 MRI showed a low signal mass (T1) and T2 MRI showed a relative low signal round mass (T2). The mass with clear margins was slightly enhanced by gadolinium (T1-Gd). The arrows show the tumor mass.
Figure 3. The histopathological findings revealed well encapsulated lesions with cystic and solid areas consisting of an eosiophilic oncocytic epithelial cell component arranged in double layers (A: examination on low power). A variable amount of lymphoid tissue represented with germinal centers (B: examination on high power).
