Submandibular gland (up to 85% of cases) followed by parotid gland (5- 10% of cases) and sublingual and minor salivary glands (1-5%).
There are multiple large calculi along right Wharton's duct. The largest most anterior stone measures 1.7 x 0.7 cm in greatest axial dimension. Notable regional edema within the sublingual space and floor of mouth. There is intraglandular ductal dilatation within the right submandibular gland which appears mildly hyper-enhancing.
Mildly prominent right level I lymph nodes are identified, likely reactive. The airway remains patent.
No soft tissue fluid collection is identified within the neck. No destructive bony lesions are identified.
