Prenatal Diagnosis of Body Stalk Anomaly at 9 Weeks of Gestation

We report on a case of embryonic anomaly detected at 9 + 5 gestational weeks. The lower part of the embryo was located in the coelomic cavity. Lower extremities could not be depicted. The abdominal wall showed the appearance of omphalocoele. After termination of pregnancy at 10 weeks, autopsy confirmed the anomaly of the lower embryonic parts consistent with the diagnosis of body stalk anomaly. To our knowledge, this is the first observation of this condition before 10 gestational weeks.
