Twin paradox: Monoamniotic twin pregnancy discordant for limb body wall complex: Presentation of a rare syndrome with a review of embryology

Early morphological assessment of the fetus at the time of the first-trimester screening scan can be of utmost importance to diagnose a polymalformative syndrome, which may be incompatible with life. An omphalocele, even in the absence of genetic or chromosomal abnormalities, may be associated with a lethal syndrome, that is, limb body wall complex. This should specifically be thought of and searched for, especially in fetuses who present with omphalocele in combination with curvature abnormalities of the spine.
