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.
