Abstract

A case of sireniform malformation in a 17-wk-old fetus is described. In addition to the characteristic fusion of the lower limbs, there were also severe malformations of the urogenital system and lower intestinal tract. The essential features and various theories of genesis are discussed. The cases so far described in literature are reviewed. Ultrasound can be very useful in early detection of this deformity, because defective movements of the single lower limb and the typical medial position of the fibulae can be seen.

摘要

本文描述了一例17周龄胎儿的美人鱼样畸形病例。除下肢特征性融合外，泌尿生殖系统和下肠道也存在严重畸形。文中讨论了其基本特征和各种成因理论，并对文献中迄今报道的病例进行了回顾。超声检查在早期发现这种畸形方面非常有用，因为可以看到单一下肢的异常活动以及腓骨的典型内侧位置。
