Fetus with a hemangioma in the left liver lobe (fetus 1). a Circular hypoechoic lesion, measuring 86 × 81 × 103 mm. Color Doppler ultrasound shows a ring of blood flow at the edge of the lesion and stars intralesion. Pulse Doppler ultrasound suggests that the resistance index is 0.33. b Ultrasound on the day of birth shows that lesion has a clear border, an excentric growth pattern, and an internal grid-shaped region and bypasses the left hepatic vein. c Postnatal computed tomography (CT) shows the lesion in the left lobe. On contrast-enhanced CT, the lesion was centripetal enhancement. d Two years after treatment of the neonate with propranolol and dexamethasone, the lesion was 35 × 36 × 34 mm in size, with multiple strong echo spots in the center
