This exhibit illustrates multimodal imaging findings of chronic sclerosing sialadenitis (CSS) with correlation of the clinical presentation and pathologic findings.  CSS is one of IgG4-related diseases which involve various organs. Radiologists should know the clinical presentation and the imaging findings of the CSS to diagnose IgG4-related disease efficiently when the other critical organ might be involved in this entity, because the diagnostic biopsy of most of those affected organs is often invasive and difficult to perform without risk, while biopsy of the salivary gland is considered safe and less invasive way to the accurate diagnosis.    

1. Introduce a history of chronic sclerosing sialadenitis from Küttner tumor in 1896 to recent concept of IgG4-related disease. 2. Review of clinical presentation of chronic sclerosing sialadenitis. 3. Review of CT, MR, PET-CT and ultrasonography of chronic sclerosing sialadenitis in comparison with resected specimens. 4. Differential diagnosis of chronic sclerosing sialadenitis. 5. Review of clinical presentation of the other IgG4-related diseases. 6. Review of CT, MR, PET-CT and ultrasonography of the other IgG4-related diseases. 7. Discussion the treatment of the IgG4-related diseases.
