Main Article Content
Abstract
Sirenomelia is a rare congenital malformation affecting multiple organ systems. The phenotypic feature is fusion of the lower extremities. We hereby present a case of sirenomelia diagnosed at an ultrasound at 12 weeks gestation. The pregnant nulliparous woman had a history of bypass surgery and a BMI of 46. The father was treated with methotrexate at the time of conception due to psoriasis. The pregnancy was by natural conception. The case study includes high quality ultrasound imaging and photos displaying the phenotype of the aborted fetus.
