History

Patient is a 69-year-old female with left leg pain.

Findings

• Radiographs of the left femur reveal a lytic lesion causing cortical destruction involving the posteromedial aspect of the proximal left femur.
• MRI of the left femur demonstrates a T2-hyperintense mass which enhances with contrast administration.
• CT of the abdomen reveals a large heterogeneously enhancing mass arising from the left kidney.
• Preoperative angiogram performed for embolization reveals an abnormal vascular blush with feeding branches arising from the left profunda femoral artery. No residual tumor blush was seen after embolization.
• Postoperative radiographs show the lesion post-curettage with placement of an intramedullary rod.

Diagnosis

Metastatic Renal Cell Carcinoma, Conventional Clear-Cell Type
