Submandibular swelling right more than left: CT showed possible early calculus: worsening and difficulty swallowing. There is an external marked overlying the right submandibular gland, which appears to be mildly swollen and hyperenhancing diffusely. There is enlargement of the right submandibular ducts extending into the sublingual space, where there is a punctate T1 and T1 hypointensity. The other salivary glands appear unremarkable. There is no evidence of mass lesions or significant lymphadenopathy in the neck. The orbits and imaged intracranial structures are unremarkable. There is multilevel degenerative spondylosis, with an intervertebral disc herniation at C4.
Findings suggestive of right submandibular sialoadenitis with ductal obstruction likely associated with a punctate calculus in the sublingual space.
