Fetal mediastinal teratomas are rare tumors that can lead to serious complications such as fetal hydrops and intrauterine fetal death. Early prenatal diagnosis is critical in patient counseling, management, and preparation for postnatal interventions. In this report, we present the case of a 27-year-old woman in the second trimester of a dichorionic diamniotic twin pregnancy, in which the presenting fetus was diagnosed with a mediastinal teratoma and subsequently developed fetal hydrops, leading to intrauterine death. The diagnosis was initially made via ultrasound and the second twin exhibited no major anomalies. Following the fetal demise of the affected twin, a cesarean section was performed due to suspected maternal complications, and the surviving twin was delivered prematurely. This case highlights the importance of multidisciplinary collaboration in the management of complex twin pregnancies and underscores the challenges of diagnosing and managing rare fetal anomalies.
胎儿纵隔畸胎瘤是一种罕见的肿瘤，可导致严重并发症，如胎儿水肿和宫内胎儿死亡。早期产前诊断对于患者咨询、管理以及产后干预的准备至关重要。在本报告中，我们介绍了一名27岁处于双绒毛膜双羊膜囊双胎妊娠中期的女性病例，其中先露胎儿被诊断为纵隔畸胎瘤，随后发展为胎儿水肿，导致宫内死亡。最初通过超声做出诊断，第二个胎儿未发现重大异常。在受影响的双胎之一胎儿死亡后，由于怀疑有母体并发症，进行了剖宫产，存活的双胎早产。该病例凸显了多学科协作在复杂双胎妊娠管理中的重要性，并强调了诊断和管理罕见胎儿异常的挑战。
