Three-dimensional ultrasonographic imaging of Mikulicz’s disease

Case Series of Changes in Greyscale and Power Doppler Signals on Salivary Gland Ultrasonography after Treatment in Patients with Sjögren's Syndrome

“…In addition to the increased blood flow in the larger branch of the facial artery and transverse facial artery, we consider minute blood flow to frequently exist at the border of oval hypoechoic areas, the boundary of which is slightly unclear in the parenchyma. However, we conversely reported a case of IgG4-related disease (IgG4-RD) with PDs that dendritically expanded and distended vessels throughout the glands located at the center of the hypoechoic areas of the nodal pattern, the borders of which were clear (20). Furthermore, the patterns of GS and PDs differed from those of SS; therefore, GS and PDs may be useful in distinguishing SS from IgG4-RD.…”
