📄 Report Sample Line - Single FDIU in Stuck Twin Syndrome

Diamniotic monochorionic twin gestation. One twin (Twin A) shows no detectable fetal cardiac activity or movements, with measurements corresponding to a gestational age of approximately 15 weeks. Twin A appears compressed against the uterine wall with oligohydramnios, consistent with "stuck twin" appearance. The amniotic sac is severely reduced in volume, and fetal anatomy is difficult to assess due to crowding. The co-twin (Twin B) with measurements corresponding to a gestational age of approximately 20 weeks demonstrates normal cardiac activity and active movements with adequate amniotic fluid volume and biometric parameters appropriate for gestational age. Placenta is single and shared. Twin-Twin Transfusion Syndrome (TTTS) Stage II–III features may be present.

Conclusion: 📋 Findings suggestive of Single Fetal Demise (FDIU) in Monochorionic Diamniotic Twin Pregnancy, with features of Stuck Twin Syndrome. Twin A: FDIU; Twin B: Viable.

Recommendation: Evaluate for complications such as anemia, neurological sequelae, or TTTS progression.
