Sonographic features of anorectal atresia at 12 weeks.
We present the sonographic features of a fetus with anal atresia at 12 weeks of gestation. Follow-up ultrasound examination at 17 week revealed apparently normal bowel. Spontaneous miscarriage occurred at 18 weeks and postmortem examination showed anorectal atresia and arthrogryposis multiplex. It seems that dilatation of the bowel in the early pregnancy is a possible marker for anorectal atresia, and the abnormality may be overlooked if a mid-trimester scan alone is performed.
