Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a rare immune-mediated fibro-inflammatory condition that can affect nearly any organ, with breast involvement (IgG4-related sclerosing mastitis, IgG4-RM) being exceptionally uncommon. This disease primarily affects middle-aged to elderly women and is frequently misdiagnosed as malignancy due to non-specific clinical and imaging features. We report a case of a 44-year-old woman with a painless right breast mass showing hypoechoic ultrasound findings and magnetic resonance imaging (MRI) characteristics, including a high ADC value and homogeneous enhancement with a persistent time-intensity curve (TIC). Histopathology confirmed IgG4-RM, with no recurrence after 12 months. A review of 24 published lectures highlights the diagnostic challenges and imaging variability of IgG4-RM.
期刊介绍：
IMMUNOLOGIC RESEARCH represents a unique medium for the presentation, interpretation, and clarification of complex scientific data. Information is presented in the form of interpretive synthesis reviews, original research articles, symposia, editorials, and theoretical essays. The scope of coverage extends to cellular immunology, immunogenetics, molecular and structural immunology, immunoregulation and autoimmunity, immunopathology, tumor immunology, host defense and microbial immunity, including viral immunology, immunohematology, mucosal immunity, complement, transplantation immunology, clinical immunology, neuroimmunology, immunoendocrinology, immunotoxicology, translational immunology, and history of immunology.
