Description of the case: A 26‐year‐old, gravida 1, para 0, female. The first scan was at 16 weeks, with normal fetal biometry and development. At 25 weeks' gestation, a cystic area at the level of the biparietal‐diameter, measuring 25 mm of diameter, ventricles has normal sizes, the cystic area was interrogated with color Doppler and showed a typical ‘turbulent flow’. The transvaginal probe was performed for evaluation of the fetal brain. Color Doppler energy was used to evaluate the cystic area and their communications –‘angiography’, followed by tri‐dimensional reconstruction of the brain vessels, especially the venous drainage and the arterial communications. This pathology is referred as a complex arterio‐venous malformation (AVM). Antenatal MRI was performed to evaluate the central nervous system. The parents were counseled about the prognosis. At 34 weeks' gestation, the shunts of the arteriovenous malformation were more prominent, ventriculomegaly, tricuspid regurgitation and polyhydramnios. Proof of diagnosis: At 35–36 weeks' gestation, she delivered a female baby, weighing 2900 g, with Apgar score 4 and 8. The baby was transferred for the neonatal intensive care, but after 24 h died because of renal failure. Relevance: This report demonstrated that 3D color Doppler energy mode is useful in prenatal diagnosis and a more detailed angio‐architecture of the aneurysm of the vein of Galen, with a excellent correlation with MRI. We hope, in the near future this technique could guide the identification of the fetus at increased risk for intrauterine and neonatal cardiac failure and therefore poor prognosis.
