Although inflammatory breast disorders are a frequently encountered clinical complaint, there is paucity in literature that describes their imaging appearance especially on MRI. They range from benign up to malignant forms, namely IBC which carries a grave prognosis. It is very important to distinguish IBC from other types of mastitis because there are major differences in its prognosis, and treatment. Ultrasonography & MRI examination are the main diagnostic tools for discriminating benign from malignant mastitis. Bright T2 signal, ill-defined collections and mild skin thickening were considered indicative of benign lesions. Dark T2 signal, absence of collections and extensive skin thickening were considered as indicative of malignant lesions. Better experience and awareness of these modalities would allow better diagnosis and prompt management of the benign & malignant forms of mastitis.
