摘要
A 64-year-old man presented with a complaint of left exophthalmos. Whole-body F-18-FDG PET/CT showed increased uptake in the soft tissue masses in the orbits, peripancreas, and left renal hilum. C-11-methionine (MET) PET/CT of the head and neck showed increased uptake in the orbits, and the SUVmax of the left orbital lesion was 7.0. The patient was finally diagnosed as IgG4-related disease by the results of increased serum IgG4 and the biopsy of the orbital lesion. Although C-11-MET is generally considered as a tumor-specific tracer, fibrous tissues of IgG4-related disease may be visualized by C-11-MET PET/CT.
