Idiopathic granulomatous mastitis is a rare, chronic inflammatory disease of the breast that frequently occurs in young women of childbearing age. The lesion usually presents as a unilateral firm breast mass with signs of inflammation but bilateral involvement has been reported. As the clinical presentation and radiological imaging of idiopathic granulomatous mastitis can mimic two common breast diseases, mastitis with abscess and breast cancer, a tissue biopsy is required for histopathological diagnosis. The etiology and ideal treatment remain unclear. Conservative treatment with immunosuppressive therapy has proven good efficacy. In this case report, we present a patient diagnosed with bilateral idiopathic granulomatous mastitis. We review and discuss the clinical presentation, imaging, diagnosis and management of this patient that eventually responds well to steroid therapy.
