The fetal biometry of both twins was consistent with the menstrual age. The upper and lower limbs of both twins were normal. Fetuses were positioned face-to-face and fused from umbilicus to lower thorax. Fetuses were found to share the heart and liver. One fetus had cystic hygroma. The parents opted to terminate the pregnancy but refused autopsy.
