Body stalk anomaly diagnosed in the 2nd trimester.

We examined a 20-year-old primigravida by ultrasound at 21 weeks of gestation during routine anomaly scanning. Several fetal deformities were demonstrated: the upper part of the body was in the amniotic cavity, while the lower part was in the celomic cavity. A large abdominal wall defect was detected with herniation of the liver and the intestine. The limbs were deformed, the spine had severe kyphoscoliosis, and the umbilical cord was very short. These findings were suggestive of a body stalk anomaly. Termination of the pregnancy was offered and decided by the parents. The pathology report confirmed the ultrasonographic diagnosis.
