Figure 1 Color Doppler ultrasound scan of the transplanted kidney. A: Rounded, 3.8 cm-sized, hypoechoic mass localized between the hilum of the allograft and the iliac vessels (blue arrow); B: Turbulent intra-lesional flow (yin-yang sign) along the renal allograft artery (blue arrow).

Figure 2 Abdominal contrast-enhanced computed tomography scan. A: Saccular dilation of the iuxta-anastomotic segment of the renal allograft artery, measuring 3.2 cm × 3.5 cm × 4.0 cm (white arrow); B: The aneurysm involves the main branch and extends to the bifurcation of the renal allograft artery (white arrow).

Figure 3 Intra-operative finding. A: Large bulging aneurysm causing pressure effects on the transplanted kidney (white arrow); B: The aneurysm is saccular, wide-necked, and involves the main branch of the renal allograft artery (white arrow).
