Abstract
- Context: Idiopathic granulomatous mastitis (IGM) is a benign inflammatory condition of the breasts with an unknown etiology, which can mimic breast cancer on conventional ultrasound. Other imaging modalities, such as mammography and magnetic resonance imaging, cannot efficiently differentiate this condition from malignancies. Elastography is a novel imaging technique used to evaluate tissue elasticity. Objectives: This systematic reviewaimed to investigate the imaging features of IGMonelastography and also to determinewhether thismodality is useful for distinguishing IGMfromother breastmalignancies. Materials and Methods: A comprehensive literature search was conducted across several databases, including Medline, Embase, Cochrane Library, Scopus, andWeb of Science, in October 2022. The Joanna Briggs Institute (JBI) critical appraisal tool was used for the quality assessment of the studies. Results: After screening 851 articles, seven studies investigating ultrasound elastographywere found tomeet the inclusion criteria. Regarding the quantitative findings, both the strain ratio and shear wave velocity were observed to be higher inmalignantmasses as compared to IGM. Additionally, qualitative scoring systems, such as the Tsukuba and Tozaki classifications, assigned higher scores to malignant lesions. Five of the included studies in this review proposed a specific cut-off point for differentiating IGM frommalignancies, using either shear wave velocity, strain ratio, or elasticity scores. In four of the studies, these criteria exhibited sensitivity and specificity of approximately 90%. Conclusion: The current findings suggest that ultrasound elastography can serve as a valuable tool for distinguishing IGM from breastmalignancies. By potentially reducing the number of unnecessary tissue biopsies, thismodalitymay lead to amore efficient patient evaluation process. [ABSTRACT FROM AUTHOR]
