The present case study reports contrast-enhanced magnetic resonance findings in three patients with histopathologically proven IgG4-related chronic sclerosing sialadenitis of the submandibular gland. All three patients presented with painless swelling of the submandibular region. The contrast-enhanced T1-weighted images showed reticular enhancement of the swollen submandibular gland. Radiological-pathological correlation revealed that the characteristic reticular enhancement corresponded to fibrosis and to inflammatory cell infiltration in the interlobular septa and in the periductal region of the submandibular gland.
