Psulated mass-like lesions, necessitating differentiation from malignant soft tissue tumors. We present a case of subcutaneous fat necrosis initially felt to be suspicious for an atypical lipoma or liposarcoma, and propose that the characteristic location and appearance of these lesions may help suggest a benign diagnosis and guide conservative management in some cases. Case report a fifty three-year-old female presented for evaluation of a palpable mass over her left greater trochanter. She recalled falling on her left hip two months earlier. The mass was not painful. She had no systemic complaints. Her past medical was remarkable for a high-grade leiomyosarcoma in the lateral compartment of the left calf, treated three years earlier with wide excision, adjuvant chemotherapy and radiation. She had no evidence of recurrent or metastatic disease. Physical examination revealed an obese female with a palpable, approximately 5 x 3 cm lesion over the left greater trochanteric region. The mass was superficial and mobile. It was not tender to palpation. The overlying skin was normal. The range of motion at her left hip was normal. Mri of the pelvis revealed a 4. 1 x 4. 6 x 4 cm round lesion of predominantly fat signal intensity in the superficial adipose tissue overlying the left greater trochanter. The lesion had a thin 1-2 mm soft tissue capsule and a few tubular soft tissue elements at its caudal aspect, which appeared to be blood vessels (figure 1). There was mild amount of edema surrounding the well-defined margin (figures 2 and 3). Post-intravenous gadolinium, there was enhancement of the blood vessels at the caudal aspect of the lesion but no enhancement of the remainder of the lesion (figure 4). The underlying femoral cortex and marrow signal was normal. Due to the patient's large body habitus, the patient's side touched the bore of the magnet which resulted in field inhomogeneity and suboptimal fat suppression. Figure 1a. Posttraumatic pseudolipoma.
