In this paper we describe sonoelastography findings for idiopathic granulomatous mastitis (IGM), the clinical and radiological features of which often mimic those of breast carcinoma.In this retrospective study, sonoelastography findings for patients with pathologically proved IGM were studied. Twenty-seven patients with pathologically proved IGM were enrolled in the study. All were female, and the mean age was 37.81 years (standard deviation 7.10 years; range 24 to 56 years). Elasticity scores (ES), strain ratios (SR), and elastic diameters (ED) were evaluated for the lesions.Ten lesions (37.0 %) were diffuse, six (22.2 %) were tubular, six (22.2 %) were a mass, and five (18.5 %) were cystic in appearance on ultrasonography. On sonoelastography, mean ES ± standard deviation was 1.66 ± 0.55 (between 1.00 and 3.00); mean SR ± standard deviation was 1.10 ± 0.79 (between 0.29 and 4.00). ED was no different between grey-scale and sonoelastogram images.The features of idiopathic granulomatous mastitis suggest it is benign in nature.
