The is a 24 mm x 21 mm x 38 mm multilobulated, well circumscribed mass lesion within the left parotid tail, demonstrating heterogeneous signal and contrast enhancement. The medial margin of the lesion contacts the left mandibular angle, however, there is no extent into the deep lobe of parotid demonstrated. There is no abnormal mandibular marrow signal and no abnormal perineural enhancement involving the left facial or V3 nerves.
The contralateral parotid gland appears unremarkable. Prominent cervical chain and submandibular lymph nodes demonstrated bilaterally, likely inflammatory.
There is an encapsulated cystic lesion associated with an unerupted right maxillary tooth with T1 high signal content that demonstrates restricted diffusion - likely representing a inspissated dentigerous cysts.
No regions of high-grade cervical canal stenosis. No abnormal cervical marrow infiltration.
The imaging morphology of the well-defined parotid lesion is in keeping with a pleomorphic adenoma involving the left parotid tail without involvement of the deep lobe of parotid.
The right parotid gland appears normal.
An inspissated, likely dentigerous cyst is noted in the right maxillary sinus associated with an unerrupted tooth.
