Submandibular duct stone

Case contributed by Frank Gaillard

Plain film demonstrates an ovoid calcific density just below the angle of the mandible. 


CT confirms the presence of calcific density on the left in a location likely to place it within the submandibular duct near the gland. The submandibular gland appears unremarkable (not enlarged; no surrounding stranding).


A sialogram confirms the presence of a submandibular duct stone located at the hilum of the gland.

Case Discussion

 The duct was subsequently cannulated and the stone removed fluoroscopically.
