“…With respect to the major advantages of HDlive, its pictures of embryos and fetuses are more readily discernible than those obtained by conventional 3D ultrasound [13]. In the fetus with sirenomelia, HDlive has been shown to allow acquisition of extraordinary image quality, including single femur, fused lower limbs, and a single inverted foot with oligodactyly [14]. Moreover, HDlive provides entirely new visual experiences for couples and their families, owing to the anatomically realistic depiction of normal fetal development and fetal anomalies [13, 15, 16].…”

Sirenomelia is a rare congenital malformation characterized by varying degrees of fusion of the lower extremities. It is commonly associated with severe urogenital and gastrointestinal malformations; however, the association of sirenomelia with anencephaly and rachischisis totalis is extremely rare. To our knowledge, the prenatal sonographic images of this association have not been previously published. Here, we present prenatal sonographic images of this association, detected during the 17th week of gestation through combined two-dimensional, four-dimensional, and color Doppler ultrasound. Two-dimensional ultrasound images showed anencephaly, spina bifida, and possible fusion of the lower limbs. Three-dimensional HDlive rendering images confirmed the final diagnosis of sirenomelia with anencephaly and rachischisis totalis. The patient opted to undergo medical termination of pregnancy and delivered a fetus with fused lower limbs, anencephaly, and rachischisis totalis confirming the in utero imaging findings. Awareness of these rare associations will help avoid misdiagnoses and facilitate prenatal counselling. This case highlights the importance of a thorough ultrasound examination.

Diagnosing fetal syndromes is a major challenge both in the prenatal and postnatal period2. The syndrome is like a big puzzle whose parts need to be carefully assembled to get a whole picture. 2 Good multidisciplinary approach, proper communication and collaboration with parents and all physician's involved are required in the diagnostic process. All available resources and tools are needed to increase diagnostic precision in the prenatal diagnosis of fetal syndromes. 4 The introduction of highly specialized software systems for three-dimensional and four dimensional ultrasound (3D/ 4D US) enable detailed assessment of the fetal anatomy and the evaluation of the dynamics of structural and functional development of the fetus in real-time. 2,4 Owing to this, clinical practice has also gained new functional tests such as the Kurjak's antenatal neurodevelopmental test (KANET); named in honor of its author; used for the evaluation of fetal brain function. 2-4,24-31 Antenatal detection and diagnosis of fetal anomalies and syndromes is shifted from the 2nd to the 1st trimester of preg

Whereas understanding normal fetal behaviour and movements in humans provides invaluable clinical perspectives for making specific diagnoses [22][23][24], studies of fetal behaviour in other vertebrates is important for understanding the evolutionary context for behavioural development.…”

Tail movements by late-term fetal pitvipers resemble caudal luring: prenatal development of an ambush predatory behaviour

With the advent of powerful imaging instruments, the prenatal behaviour of vertebrates has been discovered to be far more complex than previously believed, especially concerning humans, other mammals and birds. Surprisingly, the fetal behaviour of squamate reptiles (lizards, snakes and amphisbaenians), a group of over 11 000 extant species, are largely understudied. Using ultrasonography, 18 late-term pregnant copperhead snakes ( Agkistrodon contortrix ) from a single population were inspected for fecundity (number of fetuses). Unexpectedly, during the ultrasound procedure that involved 97 fetuses, we observed sinusoidal tail movements in 11 individuals from eight different copperhead mothers. These movements were indistinguishable from caudal luring, a mimetic ambush predatory strategy which is exhibited by newborn copperheads and other snakes. Caudal luring is initiated shortly after birth and is employed to attract susceptible vertebrate prey. Using the same ultrasound equipment and methods, we tested for this behaviour in two species of rattlesnakes (genus Crotalus ) not known to caudal lure and none of the late-term fetuses showed any type of tail movements. Prenatal movements in humans and other vertebrates are known to be important for musculoskeletal and sensorimotor development. The fetal behaviours we describe for copperheads, and possibly other snakes, may be similarly important and influence early survival and subsequent fitness.
