Breast magnetic resonance imaging: non-mass-like enhancement

Authors: Liuquan Cheng, Xiru Li


Non-mass-like enhancement (NMLE) refers to lesions with abnormal enhancement larger than focus but without space-occupying effect characteristics. Notably, it is often mentioned as “non-mass-like enhancement” rather than “non-mass lesion”. Different from mass, NMLE can have stippled or patchy normal gland tissues or fat inside it. NMLE should be described from its morphology and internal enhancement pattern (Figures 1,2).
