Figure 1 Computed tomography images from a case of retroperitoneal invasive fibroma and key steps in surgery. A: The arterial phase of the computed tomography (CT) scan indicated a massive pelvic mass with a diameter of approximately 20 cm surrounding the right internal iliac artery (white arrow) and external iliac artery (black arrow); B: The venous phase of the CT scan indicated that the mass surrounded the right common iliac vein and caused compression occlusion (arrow); C: During surgery, the right femoral artery (white arrow) was dissociated; the blue arrow indicates the mass; D: Artificial vessel reconstruction between the right common iliac artery (blue arrow) and femoral artery (black arrow) was performed after tumor removal.
