Case 1, 35-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 a high-speed low-impedance blood-flow spectrum. d: The reconstructed three-dimensional energy Doppler image clearly shows the dilated Galen vein, but no obvious straight sinus is displayed. e: MRI cross-section of the foetal skull showing the dilated Galen vein through flow phenomenon (white arrow). f: Sagittal section of the foetal brain showing dilated Galen’s venous aneurysm by flow phenomenon (white arrow)
