Conjoined twinning is a rare obstetric event that has fascinated physicians and laypersons alike for centuries. When this event occurs, early diagnosis, close prenatal management, and the proper route of delivery will assure the best possible outcome for mother and affected infants. Magnetic resonance imaging (MRI) is used both as an ancillary technique to the sonography for the antepartum diagnosis and in the preoperative planning for the surgical separation of conjoined twins. This report describes the MRI findings in conjoined twins of the thoraco-omphalopagus symmetricus type, a condition incompatible with extrauterine life. The twins were delivered at 21 weeks gestation. The MRI was used to evaluate the anatomic nature of the internal anomalies. These findings were then used to develop an autopsy approach plan that preserved the external phenotype. After dissection, the specimen was preserved by using polyethylene glycol and ultimately prepared for use as a teaching specimen.
联体双胎是一种罕见的产科情况，几个世纪以来一直吸引着医生和普通大众。当这种情况发生时，早期诊断、密切的产前管理以及合适的分娩途径将确保母亲和受影响婴儿获得尽可能好的结果。磁共振成像（MRI）既作为超声检查的辅助技术用于产前诊断，也用于联体双胎手术分离的术前规划。本报告描述了胸腹联体对称型联体双胎的MRI表现，这种情况无法宫外存活。这对双胞胎在妊娠21周时分娩。MRI用于评估内部异常的解剖性质。然后利用这些发现制定了一个保留外部表型的尸检方法计划。解剖后，标本用聚乙二醇保存，最终制备成教学标本。
