Vanishing Twin Syndrome

---

Figer-1

📄 Report Sample Line- Vanishing Twin Syndrome
a dichorionic diamniotic twin pregnancy with a single viable intrauterine fetus demonstrating appropriate crown-rump length (CRL) and cardiac activity. Adjacent to the viable gestational sac, a collapsed second gestational sac is visualized with irregular margins, absence of fetal pole or cardiac activity, and sonographic signs suggestive of involution. These findings are consistent with Vanishing Twin Syndrome.


Conclussion: 📋 Sonographic features are consistent with Vanishing Twin Syndrome in a previously confirmed twin gestation. One twin shows normal development, while the second gestational sac has regressed with no evidence of a viable embryo or cardiac activity.
Recommendation: Continue routine antenatal care with serial ultrasound monitoring for the surviving twin
