Fat necrosis.
We report the MR appearance of a case of subcutaneous fat necrosis, which is a previously unreported etiology for knee mass. The role of MR imaging in differentiating fat necrosis from other causes of soft tissue masses is discussed. We conclude that MR characteristics of subcutaneous fat necrosis are typical and allow its differentiation from other types of soft tissue lesions.
