Prenatal ultrasound-based diagnosis of fetal OEIS complex associated with lower limb polymelia and cardiac, hepatic dysplasia: A case report.

OEIS complex is a type of congenital malformation syndrome. Here, we report a case of fetal OEIS complex combined with lower limb polymelia, cardiac defects, and hepatic dysplasia. It was easily misdiagnosed when oligoamnios and the liver bulged. This case will provide reference information for early diagnosis of similar cases.
