A lobulated lesion is present in the left femoral neck and intertrochanteric region, which is isointense to muscle on T1 and heterogeneously hyperintense on T2/STIR. A portion of this lesion extends beyond the osseous confines of the anterior and lateral femoral neck, up to 1cm, in the region that cortical violation was present on CT. A small amount of fluid-like signal (edema) extends along the adjacent intermuscular fascial planes. A small hip joint effusion is present. All other intraosseous marrow signal is normal, and no satellite lesions or enlarged lymph nodes are identified.
