Presentation
Periprandial submandibular pain.
Patient Data
Each duct of the submandibular salivary glands (Wharton's ducts) showed two stones, the largest is approximately 5 mm in size. On the right side, a proximal stone is noted at the hilum of the gland while a distal stone is noted about 1 cm proximal to the terminal ostium. On the left side, a proximal stone is noted at the hilum of the gland while a distal stone is noted at the terminal ostium. Both ducts are mildly dilated reaching 4.5 mm.
Both submandibular glands are average in size with no abnormal enhancement. Mild bilateral intraglandular ducts dilatation with no evidence of associated sialadenitis. No definite intraglandular stones.
Case Discussion
The submandibular glands are the commonest site of sialolithiasis. Stone formation occurs in the Wharton's duct or intraglandular or both. Sialolithiasis can predispose to sialadenitis.
