Retrograde Transpubic Approach for Percutaneous Radiofrequency Ablation and Cementoplasty of Acetabular Metastasis

Figure 1

60-year-old-female with metastatic lung cancer complaining of left hip pain. (a) Nonenhanced axial CT image demonstrates left anterior acetabular osteolytic lesion (arrowhead) with anterior cortical thinning and posterior cortical breach. (b) and (c) The acetabular lesion (arrowhead) shows low signal intensity on axial T1W image (b) and high signal intensity on axial STIR image (c). Note its close relationship with the femoral neurovascular structures precluding a direct anterior approach (open arrow). (d) Coronal oblique reformatted CT image shows the needle path from the skin entry to the target lesion (long arrow).
