Abstract
Anatomical anomalies in the salivary glands, such as ductal ectasia and stenosis, are rare and can be idiopathic, congenital, or acquired origin. Diagnosis of these anomalies are based on imaging exams and are sometimes challenging. A 65-year-old female patient complained of a recurrent volume increase in the right preauricular region for 43 years. The swelling was exacerbated in the periprandial periods. Physical examination revealed a flaccid swelling, which aspiration was compatible with saliva. Ultrasonography and magnetic resonance imaging (sialo-MRI) showed changes in the ductal anatomy and a sialocele. The sialo-MRI allowed the diagnosis of sialocele secondary to idiopathic duct anomalies, ectasias, and strictures in the parotid ducts. The treatment performed was sialendoscopy. A good clinical evolution with significant reduction of swelling in the preauricular region was noticed. Sialendoscopy is an image-guided procedure that allows diagnosis and treatment of changes in the duct of the major salivary glands.
