Infections of the Salivary Glands
Inflammatory conditions of the salivary glands usually present with pain and swelling. The more acute inflammatory conditions are usually associated with obstruction of a major salivary duct. The more chronic conditions include recurrent sialadenitis, Sjogren's syndrome, and Mikulicz's disease. Plain films may be helpful in identifying any radiopaque calculi, but sialography is usually necessary to identify the specific location of an obstructing stone or stricture. CT is helpful for evaluation of cases complicated by either an abscess formation or involvement of adjacent soft-tissue compartments of the face.
