Painless left parotid mass. There is a well-defined, but bosselated T2 hyperintense and heterogeneously enhancing mass centered in the superficial portion of the left parotid gland, measuring up to 3 cm. The other salivary glands are unremarkable. There is no evidence of significant cervical lymphadenopathy. There are small probable retention cysts in the bilateral maxillary sinuses and left sphenoid sinuses, as well as mild scattered paranasal sinus mucosal thickening. The imaged intracranial structures and orbits are unremarkable. There is multilevel degenerative cervical spondylolysis.
