Breast focal fibrocystic changes (FCC) are a rare form of fibrocystic breast disease and a benign condition that may be present as a non-mass enhancement (NME) in magnetic resonance imaging (MRI) due to an inflammatory process caused by cyst fluid extravasation to surrounding tissues. This enhancement canmimic a malignant lesion, especially if not correlated to a cystic area detected on T2-weighted image (T2WI) in the enhancement site. In this study, we aim to describe the imaging characteristics of FCC, that is a benign lesion, Breast Imaging Reporting and Data System category 2 (BI-RADS 2), through analysis of T2WI and post-contrast sequences, to illustrate how a simple cyst or clustered microcysts on T2WI image may be found in the NME area allowing the diagnosis of FCC.
