Description
Neurographics Case Conversations: Imaging of Common and Uncommon Manifestations of IgG4-Related Disease in the Head and Neck
Description & Learning Objectives
Article Description: Immunoglobulin G4-related disease (IgG4-RD) is a
multisystemic immune-mediated disease, encompassing several conditions
previously thought to be unrelated, which can mimic malignant, infectious, and
inflammatory disorders. Head and neck IgG4-RD most frequently affects the
salivary glands and orbit; however, it can involve virtually any subsite.
Diagnosis is challenging and relies on the clinical presentation, serum
immunoglobulin G4 levels, and histopathology. Although imaging is nonspecific,
growing knowledge of IgG4-RD allows
characterization of imaging patterns and description of novel findings. This review focuses on cross-sectional imaging findings of extracranial IgG4-RD in the head and neck, presenting
cases in frequent and unusual subsites, with some cases with few descriptions in the radiological literature, such as the pharynx and larynx, temporal bone, paranasal sinuses, and perivascular areas.
Upon completion of this activity, participants will gain strategies to:
-Recognize the most common manifestations of IgG4-RD in the head and neck.
-Consider IgG4-RD as a differential diagnosis, along with other potential conditions.
