Immunoglobulin G4-related disease (IgG4-RD) is a novel, immune-mediated, multisystem disease characterized by the development of tumefactive lesions in multiple organs. IgG4-RD encompasses many fibroinflammatory diseases that had been thought to be confined to single organs. Delayed diagnosis or misdiagnosis as malignancies leading to aggressive treatment may be averted by identification of the multisystem nature of IgG4-RD. Most cases show exquisite response to steroid therapy; steroid-resistant cases are being treated by novel therapeutic agents, including B-cell depleting agents such as rituximab. Cross-sectional imaging studies play a pivotal role in the initial diagnosis, assessing response to therapy and long-term surveillance.

The utility of FDG-PET/CT and other imaging techniques in the evaluation of IgG4-related disease.

Joint Bone Spine 2014 Jul 22;81(4):331-6. Epub 2014 Feb 22.

Division of Rheumatic Diseases, National Center for Global Health and Medicine, 1-21-1 Toyama, Shinjuku, Tokyo, 162-8655 Japan.

Objectives: This study aimed to evaluate the utility of imaging techniques, including 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), in immunoglobulin (IgG)4-related disease (IgG4-RD).

Methods: We reviewed eight IgG4-RD patients who were referred to our hospital between August 2006 and April 2012. All cases underwent FDG-PET/CT and brain magnetic resonance imaging (MRI) and endobronchial ultrasonography (EBUS) were also performed in five cases and one case, respectively. Read More

Objectives: The purpose of this work is to evaluate the usefulness of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging in management of IgG4-related disease (IgG4-RD) by retrospective analysis of PET/CT results in IgG4-RD patients.

Methods: Twenty-six patients diagnosed with IgG4-RD according to Japanese diagnostic criteria who underwent 18F-FDG-PET/CT scans in the PLA General Hospital from January 2010 to May 2015 were enrolled in the study. Their clinical presentations and 18F-FDG-PET/CT findings were analysed. Read More

Purpose: We investigated the capacity of F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) to differentially diagnose immunoglobulin G4-related disease (IgG4-RD) in clinically suspected patients.

Materials And Methods: Subjects were 94 clinically suspected patients who had tissue IgG4 staining (n = 85) or serum IgG4 greater than 135 mg/dL (n = 9) and underwent FDG PET/CT within 40 days. Clinical, serologic, pathological, and PET/CT findings were analyzed. Read More

Background: Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibro-inflammatory condition with involvement of different organs. The pathophysiological mechanism is unclear, but fibrosis is the hallmark of this disease. Early recognition is critical to avoid irreversible organ damage. Read More
