ANAMNESIS / SYMPTOMS:
A 36 year old patient shows recurrent postprandial occuring swellings in the region of the left submandibular gland.



FINDINGS
:
Starting from the submandibular gland and reaching through the whole floor of the mouth and up to the chin a hypoechoic band is visible that shows no blood flow on the colour encoded Dopplerīs sonogramm. The submandibular gland, the mylohyoid muscle and the tongue are clearly visualized.


DIAGNOSIS:
The patient is suspected of suffering from a stenosis of or a small concrement in the Wharton´s duct. Stones that are located very far distally can be diagnosed on a sonogramm only by indirect signs such as a stasis of saliva in the duct. In most of the cases the stones then are visible in the area of the ductīs ostium at clinical inspection like it was in the case of this patient.
