Abstract

We report a case of an accessory submandibular gland and duct which is extremely rare.

Material and methods: A 20-year-old male presented with complaints of painful swelling in the right submandibular region. As a part of the radiological investigation, a radiograph occlusal view was taken digital sialography, magnetic resonance imaging and magnetic resonance sialography were performed.

Results: Digital sialography revealed a small calculus distal to the punctum with diffuse dilatation of the main duct and intraglandular branches, which passed out spontaneously prior to magnetic resonance examination. The presence of an accessory submandibular duct was well delineated on both digital as well as magnetic resonance sialography.

Conclusions: Magnetic resonance sialography is helpful in delineating the anatomy of the submandibular duct non-invasively and without associated radiation exposure. To the best of our knowledge this is the first report of magnetic resonance identifying an accessory submandibular duct and gland.
