Case 2, 30-week prenatal ultrasound and MRI images of a VGAM foetus. a: Two-dimensional ultrasound shows a huge thin-walled echoless area next to the midline of the brain. b: Colour Doppler shows a full blood-flow signal in the brain’s echoless area. c: The skull’s echoless area shows arteriovenous leak with arteriovenous mixed spectrum; d: The reconstructed three-dimensional energy Doppler image clearly shows the dilated VGAM, and obvious straight sinus is displayed (white arrow). e: MRI cross-section of the foetal skull showing the dilated VGAM through flow phenomenon (shown by white arrow). f: Sagittal section of the foetal brain showing the dilated Galen’s venous aneurysm by flow phenomenon (white arrow)
