Fig. 6From: DW-MRI of the breast: a pictorial reviewSix different false positive lesions on ADC maps. A highly cellular fibroadenoma is seen as a heterogeneous, focal dark area (arrow). Cyst with thick content (curved arrow) shows fluid-fluid level with dependent portion being thicker. A juvenile fibroadenoma with high cellularity (surrounded by a dashed line, pay attention to the small and normal sized left breast) demonstrates different diffusion features most of which with restriction. Breast abscesses (stars) are restricting diffusion. Note the thickened breast skin marked by white arrowhead. Mastitis (black arrowheads) can show diffusion restriction due to inflammatory cell migration and vascular fibroblastic proliferationBack to article page
