title: Echogenic fetal bowel in the third trimester associated with trisomy 18.
abstract: We present the first case of trisomy 18 in which echogenic fetal bowel was detected in the third trimester after normal echogenicity was documented during the second trimester. Fetal karyotyping should be considered in cases of increased echogenicity of the fetal lower abdomen in the second as well as the third trimester.
