Small nodule in the left breast skin adjacent to the nipple showing marked restriction of diffusion (b value 800) and plateau contrast enhancement (green). Note fatty replacement of breast tissue by the TRAM flap. The patient has had subcutaneous mastectomy with removal of tumour and remaining breast tissue and immediate (rather than delayed) TRAM flap reconstruction to fill the defect. Tumour has recurred in the skin. Note susceptibility artefact from surgical clips.
