Sialocele is a subcutaneous cavity containing saliva, caused by trauma or infection
in the parotid gland parenchyma, laceration of the parotid duct or ductal stenosis
with subsequent dilatation. It is characterized by an asymptomatic soft and mobile
swelling on the parotid region. Imaging studies are useful and help establishing the
diagnosis, such as sialography, ultrasonography, computed tomography and magnetic
resonance imaging. This paper describes a recurrent case of a parotid sialocele in a
young female patient. She presented a 6 cm x 5 cm swelling on the left parotid
region. The ultrasonographic scan of the area revealed a hypoechoic ovoid well
defined image suggesting a cyst. A sialography of the left parotid showed a cavitary
sialectasia in a panoramic and anteroposterior view. A conservative management was
adopted by percutaneous needle aspiration of the swelling, which was useful to
provide material for analysis and helped healing. Dentists should be aware of this
pathology and the importance in adopting a conservative treatment whenever it is
possible.
