Abstract

We describe a case of a 57-year-old woman with isolated immunoglobulin G4-related disorder affecting her lacrimal glands. Pre-treatment 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG PET/CT) showed diffuse enlargement and increased FDG uptake in both lacrimal glands. After immunosuppressive treatment, 18F-FDG PET/CT showed no significant FDG uptake, and the sizes of both glands returned to normal.
