Figure 2 Computed tomography images of a case of myxofibrosarcoma and key steps in the surgery. A: A layer of the arterial phase of the computed tomography scan indicated a retroperitoneal mass with a diameter of approximately 9 cm surrounding the abdominal aorta (white arrow) and adherent to the inferior vena cava (red arrow); B: Another layer indicated that the mass surrounded the left common iliac artery (white arrow); C: During surgery, the left external iliac artery (lower left arrow) and abdominal aorta (upper right arrow) were dissociated; the blue arrow indicates the mass; D: “Y-type” artificial vascular reconstruction of the abdominal aorta (white arrow), right common iliac artery (black arrow), and left external iliac artery (blue arrow) was performed after tumor removal.
