Radiograph demonstrates an ill-defined lucent lesion in the subtrochanteric proximal right femur with pathologic fracture. CT shows multiple soft tissue dense lesions in both femurs and in the left posterior iliac bone, here with cortical breakthrough and extra-osseous extension. Biopsy of this lesion demonstrated metastatic lung cancer. Additional bone metastases are shown as areas of increased tracer uptake on bone scan.
