Sjögren syndrome: A case report.

Sjögren syndrome is a systemic autoimmune disorder that affects the exocrine glands. The authors present the case of a 50-year-old woman diagnosed with this syndrome on the basis of clinical and serological findings. Sonography of the major salivary glands revealed normal-sized glands with echo structures that were diffusely inhomogeneous due to the presence of multiple hypoechoic areas. Parenchymal vascularization was significantly increased on color Doppler imaging. These findings confirmed the diagnosis and revealed active disease manifested by glandular hypervascularization. This represents a typical case of Sjögren syndrome and illustrates the diagnostic value in these cases of salivary gland sonography, which is effective, noninvasive, and repeatable and provides accurate information on the vascularization status of the glands.
