Fig. 1C —60-year-old woman with a history of right mastectomy for recurrent extensive ductal carcinoma in situ followed by deep inferior epigastric perforator (DIEP) flap reconstruction. MRI was performed for 6-month follow-up of the contralateral left breast, which had probably benign enhancing foci on initial staging MRI. Sagittal T1-weighted fat-saturated contrast-enhanced image shows enhancing fat necrosis (arrowhead) at the periphery of the DIEP flap. Clinical management: Fat necrosis was included in the differential diagnosis because of peripheral location in the flap and fat signal in the mass; however, biopsy was recommended because of thick, irregular rim enhancement and patient risk factors. Core needle biopsy showed fat necrosis with histiocytic infiltrate and focal foreign body giant cell reaction.
