Sialolithiasis

Abstract

Sialolithiasis is a rare condition characterized by the presence of stones within the salivary gland or duct. Salivary duct stones have an incidence of 1% at autopsy, but only 50 in 1,000,000 present symptomatically per year. Possible signs and symptoms include an upper neck or jaw mass that enlarges and recedes following meals and xerostomia, or dry mouth. Sonography has been used along with a number of other imaging modalities to diagnose this condition. The use of real-time sonographic imaging allows for identification and confirmation of the presence of stones within the salivary gland. Treatment of sialolithiasis generally begins conservatively but can result in surgery if not resolved. This case report demonstrates the use of sonography as an effective method of diagnosing sialolithiasis in a patient with classic symptoms.
