Background:
Accessory submandibular gland is a very rare anatomical variant. There have been only 6 reported cases of this entity in the English literature, only 1 of which was identified using magnetic resonance imaging.
Methods:
We report the case of a 39-year-old female with symptoms of left submandibular sialoadenitis who was diagnosed of sialolithiasis within the left accessory submandibular gland by magnetic resonance sialography (MR-Si).
Results:
The calculus was palpated near the submandibular papilla and was extracted by an intraoral approach. One-year follow-up revealed no evidence of recurrence.
Conclusions:
This is the first case reported to date in the English literature of a patient with sialolithiasis within an accessory submandibular gland diagnosed by MR-Si.
