Enhanced CT scan of the liver in case 1. (A,B) CT images of the infant at 8 days old reveal a large arteriovenous fistula in the right hepatic lobe. The black arrow indicates the dilated hepatic vein. (C,D) A repeated CT scan after 9 months of propranolol treatment reveals that the hepatic arteriovenous fistula was significantly reduced. CT, computed tomography.

An enhanced computed tomography (CT) scan of the liver revealed a large arteriovenous fistula in the right hepatic lobe (Figures 1A,B). At 9 months, CT indicated that the arteriovenous fistula had significantly reduced (Figures 1C,D).
Enhanced CT scan and color Doppler examinations of the liver in case 2. (A,B) CT images of the infant at 3 days old. (C) Color Doppler analysis of the liver at 3 months after metoprolol treatment. (D) Color Doppler analysis of liver at 8 months after metoprolol treatment.

An enhanced CT scan of the liver revealed a large arteriovenous fistula in the right hepatic lobe (Figures 2A,B). At 3 months of age, a repeated color Doppler ultrasound analysis of the liver suggested that the arteriovenous fistula had decreased in size (Figure 2C). At 8 months of age, color Doppler ultrasound of the liver suggested that the arteriovenous fistula had disappeared (Figure 2D).
