A 68-year-old woman was admitted with bleary eyes and lacrimal gland swelling. A biopsy specimen from a right paravertebral mass lesion detected by computed tomography showed remarkable IgG4-positive plasma cells. Because serum IgG4 was elevated to 3300 mg/dl, IgG4-related disease was diagnosed, with the assistance of fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT). Administration of 30 mg of oral prednisolone effectively reduced the lacrimal gland swelling and paravertebral mass volume. Nine months after the initiation of prednisolone, serum IgG4 was reduced to 31.4 mg/dl, and there was norecurrence.
