title: Prenatal diagnosis of nonmosaic trisomy 9 and related ultrasound findings at 11.7 weeks.
abstract: Trisomy 9 is a relatively rare chromosomal abnormality. There have been no reports of first trimester ultrasound findings associated with mosaic or nonmosaic trisomy 9 in the literature. A case of nonmosaic trisomy 9 diagnosed prenatally with ultrasound findings at 11.7 weeks gestation is presented along with associated abnormal ultrasound findings.
