Submandibular sialolithiasis


Sialolithiasis ( salivary gland stone disease ) is the single commonest disorder of the salivary glands.

Of this, the vast majority ( more than 80 % ) occurs in the submandibular gland.

Limited CT is excellent at identifying salivary duct stones and in the acute presentation may identify gland enlargement and inflammation in keeping with sialadenitis.

MRI delineates the gland and the ductal architectural even more clearly, especially the intra-glandular duct dilatation as in this case.

Traditional sialography although the gold standard is less commonly required.
