Fat Necrosis Simulating Breast Malignancy Following Reduction Mammoplasty: A Case Report

that can be the result of trauma (iatrogenic or noniatrogenic) or may have an idiopathic cause (1). Reduction mammoplasty also invokes extensive soft tissue injury and this occasionally leads to fat necrosis. Fat necrosis is often depicted on mammography as characteristic round calcifications with lucent centers (oil cysts) or as dense amorphous solid calcifications (2). On occasion, however, fat necrosis may have atypical imaging and physical examination features that are indistinguishable from malignancy (3). We report a case of fat necrosis simulating malignancy by mammography and ultrasonography, which developed in the breast following reduction mammoplasty.
