Crown-rump length discordance in dichorionic twins in the first trimester: different obstetric outcomes
First trimester intertwin crown-rump length (CRL) discordance has been suggested to predict adverse perinatal outcomes. In dichorionic diamniotic pregnancies its etiology is poorly understood. We report the cases of two sets of dichorionic twins with crown-rump length discordance diagnosed in the first trimester of pregnancy with different obstetric outcomes. In the first case, no specific cause to justify the discordant growth was found, with the pregnancy ending in a preterm birth due to severe intrauterine growth restriction of fetus 2. The second case was associated with triploidia of the smallest fetus, with normal development and birth of the co-twin. The role of first trimester ultrasound in predicting an adverse perinatal outcome is still controversial and the optimal management of twin pregnancies with CRL discordance is a challenging question.
