Abstract

Echogenic papillary muscles are noted in 30% of fetuses with trisomy 13. All reported fetuses with trisomy 13 and echogenic papillary muscles have exhibited additional abnormal sonographic findings. A 21.7-week fetus demonstrated three papillary echogenicities in each cardiac ventricle during ultrasound examination. Chromosomal analysis of amniocytes showed the karyotype 47,XX,+13. Multiple bilateral papillary muscles may provide the only sonographic sign of fetal trisomy 13.
