📄 Report Sample Line - Vein of Galen Malformation

Cranial ultrasound reveals a well-defined, midline anechoic to hypoechoic cystic lesion located posterior and superior to the third ventricle, consistent with a dilated median prosencephalic vein (vein of Galen). Color Doppler demonstrates turbulent flow with arterialized waveform, confirming arteriovenous shunting. There is mild ventriculomegaly due to impaired cerebrospinal fluid drainage. No evidence of intracranial hemorrhage or hydrocephalus at present. Fetal cardiac assessment shows cardiomegaly with signs of high-output physiology. No other structural anomalies are identified. Amniotic fluid volume is within normal limits.

Conclusion: 📋 Findings are consistent with a Vein of Galen Arteriovenous Malformation, with associated mild ventriculomegaly and cardiac changes suggestive of high-output failure.

Recommendation: Recommend fetal MRI for detailed neurovascular mapping. Serial echocardiographic follow-up to assess cardiac function. Early referral to a fetal medicine specialist and neonatal neurology team is advised for counseling and multidisciplinary planning. Postnatal embolization may be considered depending on clinical status at birth.
