Oblique radiograph of right proximal femur shows a lytic lesion with clearly-defined nonsclerotic margins involving the medullary space of the intertrochanteric region, extending into the proximal diaphysis. Endosteal scalloping and cortical thinning is observed. Additionally, several linear internal septations are noted. There is no evidence of cortical break-through or adjacent soft tissue mass and no definable matrix.
 
Coronal T1-weighted MR image shows a uniformly hypointense mass with a sharp, thin transition zone.
 
Axial fat-suppressed T2-weighted MR image shows a fluid-fluid level with intermediate signal fluid below the horizontal and a larger component of diffusely hyperintense signal above the horizontal line, representing less dense fluid.
 
Coronal fat-suppressed contrast-enhanced T1-weighted MR image shows thin enhancement of the margins of this uniformly hypointense process.
