Salivary gland tumors are relatively uncommon. Because of the importance of identifying small calculi in the gland or salivary duct as the cause of the symptom complex, nonenhanced computed tomography is often the best initial study for the evaluation of the painful gland. Ultrasound can also be used to demonstrate abnormal salivary gland architecture, with the benefit of being non-invasive. Although minor salivary gland biopsy yielding a focus score of 1 or greater is still considered a diagnostic gold standard for SS, salivary gland imaging has significant va lue in the evaluation of SS owing to the disease predilection for glandu-lar involvement [11].
