A case of bilateral idiopathic granulomatous mastitis in a 67-year-old woman is described. The clinical presentation and mammographic findings raised strong suspicions of malignancy, excluded by the histological examination, which made it possible also to rule out possible known causes of granulomatous inflammation of the breast.
