Figure 1.

Coronal CT reconstruction (A) of a 59-year-old male patient presenting with a swelling at the angle of the mandible. Note the enlarged submandibular gland (asterisk) at the right side with dilated Wharton's duct (arrow). Axial CT scan (B) of the same patient shows a contrast enhancing mass (arrow) at the anterior floor of the mouth (squamous cell carcinoma) as aetiology of the dilated Wharton's duct and the retro-obstructive sialadenitis of the right submandibular gland. Sagittal reconstruction (C) again exemplifies the tumour at the anterior floor of the mouth (arrow) and the dilated Wharton's duct (asterisk).
