There is an intramuscular lobulated soft tissue mass centered on the left masseter and temporalis muscles with extension to the superficial parotid lobe as well as the parotid duct. It appears of low signal intensity on T1WI, high signal intensity on T2WI with foci of a low signal indicating the presence of phleboliths. On dynamic post-contrast, T1WI fat sat sequences this mass shows a progressive centripetal fill-in with a relatively homogeneous enhancement on delayed sequences. There is an extension to the retromolar trigone, soft tissue of the para-mandibular region, infratemporal fossa and buccal fat pad.
