[Idiopathic granulomatous mastitis and breast carcinoma: What difference on elastography?]
1Service de radiologie et d'imagerie médicale, Centre Pierre et Marie Curie, Alger, Algérie.
Objectives:
To determine the elastographic characteristics of idiopathic granulomatous mastitis compared to breast carcinoma.
Materials And Methods:
Retrospective study of 63 breast masses. Ultrasound B mode and strain elastography were performed for each mass. Qualitative criteria (strain score) and semi-quantitative criteria (strain and length ratio) of strain elastography were studied. The pathological findings were used as the reference standard.
Results:
Sixty-three breast masses, there were 15 idiopathic granulomatous mastitis and 48 breast carcinomas. The mean strain ratio of idiopathic granulomatous mastitis was significantly lower than that of breast carcinoma, respectively 3.34±2.50 and 21.22±20.57 (P<0.0001). However, there was no significant difference between the mean length ratio of idiopathic granulomatous mastitis and breast carcinoma, respectively 1.17±0.18 and 1.22±0.23 (P=0.381).
Conclusion:
Breast elastography helps to differentiate idiopathic granulomatous mastitis from breast carcinoma.
