Conjoined twins represent a rare type of monoamniotic twins. Ultrasound assessment during the first trimester can facilitate the diagnosis, however further assessment by colour Doppler studies, 3D imaging, fetal echocardiography and fetal magnetic resonance imaging (MRI) is usually required in order to determine the specific fetal abnormalities and to guide appropriate pregnancy management. This case report presents a rare case of conjoined twins complicating a dichorionic-diamniotic triplet pregnancy, achieved after intracytoplasmic sperm injection (ICSI) and blastocyst transfer. A 44-year-old woman was referred for chorionicity determination to our Fetal Medicine Centre due to suspicion of conjoined twins in a triplet pregnancy. Ultrasound assessment at 11 weeks demonstrated a dichorionic triplet pregnancy which was also complicated by a rare type of conjoined twins (thoracoomphalopagus) and after a successful embryo reduction a neonate of 2200 g was delivered by caesarean section at term. The accurate diagnosis and early detection of conjoined twins by a fetal medicine specialist is crucial, especially as far as multiple pregnancies with three or more fetuses are concerned.
联体双胎是单羊膜囊双胎的一种罕见类型。孕早期的超声评估有助于诊断，但通常还需要通过彩色多普勒检查、三维成像、胎儿超声心动图和胎儿磁共振成像（MRI）进行进一步评估，以确定具体的胎儿异常情况并指导适当的孕期管理。本病例报告呈现了一例罕见的联体双胎合并双绒毛膜双羊膜囊三胎妊娠的病例，该妊娠是通过胞浆内单精子注射（ICSI）和囊胚移植实现的。一名44岁女性因三胎妊娠疑似联体双胎被转诊至我们的胎儿医学中心进行绒毛膜性判定。孕11周时的超声评估显示为双绒毛膜三胎妊娠，同时还合并一种罕见类型的联体双胎（胸腹联体双胎），成功减胎后，足月时通过剖宫产分娩出一名体重2200克的新生儿。胎儿医学专家对联体双胎的准确诊断和早期检测至关重要，尤其是对于三胎或更多胎儿的多胎妊娠而言。
