Abstract

Purpose: IgG4-related disease (IgG4-RD) is an increasingly recognized clinicopathological disorder with immune-mediated inflammatory lesions mimicking malignancies. A cohort study was prospectively designed to investigate the value of (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in characterizing IgG4-RD.

Methods: Thirty-five patients diagnosed with IgG4-RD according to the consensus criteria were enrolled with informed consent. All patients underwent baseline (18)F-FDG PET/CT evaluation. Among them, 29 patients underwent a second (18)F-FDG PET/CT scan after 2 to 4 weeks of steroid-based therapy.

Results: All 35 patients were found with (18)F-FDG-avid hypermetabolic lesion(s); 97.1% (34/35) of these patients showed multi-organ involvement. Among the 35 patients, 71.4% (25/35) patients were found with more organ involvement on (18)F-FDG PET/CT than conventional evaluations including physical examination, ultrasonography, and computed tomography (CT). (18)F-FDG PET/CT demonstrated specific image characteristics and pattern of IgG4-RD, including diffusely elevated (18)F-FDG uptake in the pancreas and salivary glands, patchy lesions in the retroperitoneal region and vascular wall, and multi-organ involvement that cannot be interpreted as metastasis. Comprehensive understanding of all involvement aided the biopsy-site selection in seven patients and the recanalization of ureteral obstruction in five patients. After 2 to 4 weeks of steroid-based therapy at 40 mg to 50 mg prednisone per day, 72.4% (21/29) of the patients showed complete remission, whereas the others exhibited > 81.8% decrease in (18)F-FDG uptake.

Conclusion: F-FDG PET/CT is a useful tool for assessing organ involvement, monitoring therapeutic response, and guiding interventional treatment of IgG4-RD. The image pattern is suggested to be updated into the consensus diagnostic criteria for IgG4-RD.

Trial registration: ClinicalTrials.gov NCT01665196.

A 54-year-old man with IgG4-related disease showed multi-organ involvement (a whole-body view; b salivary glands; c pancreas; d prostate), significant response after two weeks of steroid-based treatment (eh), and characteristic immunohistochemical stains of submandibular gland specimen (i HE stain; j CD38-positive plasma cells; k IgG-positive cells; l IgG4-positive cells. The IgG4-positive cells were > 60 % of the IgG-positive cells)

18F-FDG PET/CT guided the timely ureter recanalization in an IgG4-RD patient with retroperitoneal fibrosis and aorta involvement. The enlarged right renal pelvis with radioactive urine retention indicated severe ureteral obstruction, whereas the left side without radioactivity indicated complete obstruction (a and b). After D-J tube cannulation, the renal function was recovered bilaterally (c and d); the intense-uptake lesions were smaller and the intensity was significantly lower in response to the steroid treatment. The arrows show the aorta involvement beside the retroperitoneal fibrosis (e, f), which has a complete response to steroid-based treatment (g, h)
