Oligohydramnios, an aberrant vitelline artery leading to a single umbilical artery, and a fetal abdominal cyst that occupies most of the abdominal cavity in the second trimester are considered as fetal sirenomelia associated with large defects of the gastrointestinal and genitourinary tracts, and the fetus is more likely to be incompatible with life.
