Abstract
A 72-year-old man was referred to our hospital because of right renal tumors. Ultrasound examination revealed two masses in the right renal hilum. Contrast-enhanced computed tomography (CT) scan showed 25 mm and 10 mm soft tissue density nodules with poor contrast effect in the right renal hilum. Positron emission tomography-CT scan showed an accumulation of SUVmax of 6.65 in the same area. A CT-guided biopsy was performed, and immunostaining revealed the presence of IgG4-positive plasma cell clusters and a high serum IgG4 level of 658 mg/dL. A definitive diagnosis of IgG4-related disease was made, and the patient was placed under observation.A CT-guided biopsy is helpful for the diagnosis of IgG4-related disease and should be considered when masses are found in the unilateral renal hilum.
