Difficulties of Differential Diagnostics of Idiopathic Granulomatous Mastitis with Contrast Enhanced Visualization Methods

Mastitis is an inflammatory condition of the breast, which may or may not be accompanied by infection (WHO 2000).
Idiopathic granulomatous mastitis is one of the forms of non-infectious mastitis. Granulomatous lobular mastitis is a rare inflammatory disease of the breast that was first described by Kessler and Wolloch in 1972.
Idiopathic granulomatous mastitis (IGM) or granulomatous lobular mastitis is chronic inflammatory breast disease of unknown etiology, the clinical manifestation and radiological features of which may mimic other nosological entities.
We report a case of 29 year old woman who was diagnosed with breast carcinoma by radiological methods, such as contrast enhanced spectral mammography (CESM), magnetic resonance imaging with dynamic contrast enhancement (MRI with DCE), SPECT/CT. However, performed core needle biopsy of a lesion shows no tumor cells. The conservative treatment was suggested, based on obtained information.
Aim is a review of radiological features of IGM with contrast enhanced visualization methods, based on our clinical case; description of differential radiological features in comparison with similar diseases of the breast, such as inflammatory breast carcinoma, tuberculosis etc.
