title: Imaging features of idiopathic granulomatous mastitis - Case report.
abstract: Idiopathic granulomatous mastitis is a rare disorder of unknown etiology. This disease occurs mostly in young women and often after the lactation period. Women usually present with a fixed, painful mass, sparing the retroareolar region, associated with skin thickening and possible ulceration that mimics carcinoma. Nipple discharge can be present and bilateral involvement may occur in up to 25% of cases. In this case report, we present a typical case of histologically confirmed idiopathic granulomatous mastitis, highlighting the imaging findings, including magnetic resonance imaging (MRI), which may favor this diagnosis and enable better clinical management of these patients.
