Abstract

Sirenomelia, characterised by a complete or incomplete fusion of the lower extremities, is a severe form of caudal defect affecting 1 in 60,000 births. Most cases of sirenomelia die within 5days after birth and are associated with abnormalities such as renal agenesis, urinary tract agenesis, single umbilical artery, etc. Thirdtrimester ultrasonographic diagnosis is usually impaired by severe oligohydramnios whereas the amount of amniotic fluid may be efficient to allow diagnosis in the late first trimester. We report of a case of sirenomelia at 14 weeks of gestation using prenatal transvaginal and transabdominal ultrasonography.
