Preoperative imaging findings. Non-contrast computed tomography (CT) showed a mass continuous with the left common iliac artery (A). Contrast-enhanced CT revealed occlusion of the left common iliac artery and a retroperitoneal mass with high CT values (B). T1-weighted magnetic resonance imaging (MRI) demonstrated a retroperitoneal mass with high signal intensity (C). T2-weighted MRI demonstrated the same mass with low signal intensity, located posterior to the distal left external iliac artery (arrowhead) (D).
