Case contributed by Dr Safwat Mohammad Almoghazy

Presentation

A known case of follicular lymphoma in clinical remission post treatment under follow-up.

Patient Data

Age: 40 years
Gender: Male

Bilateral accessory parotid glands are seen lateral to the masseter muscles, both anterior and separate from the main parotid glands.

Accessory parotid glands have their own blood supply and secondary ducts appearing emptying directly into the mouth separated from Stensen's duct.

The CT attenuation is similar to the main parotid glands.

Bilateral accessory parotid glands (yellow arrows) are seen lateral to the masseter muscles and both anterior and separate from the main parotid glands (yellow stars).

Case Discussion

Accessory parotid glands are a common variation and can be observed incidentally. They should be not mistaken with pathological lesions. Accessory parotid glands on CT or MRI show similar density or signal intensity as the main parotid gland as seen in our case.
