Introduction

Limb–body wall complex (LBWC) refers to a combination of multiple malformations involving the craniofacial structures, thoracoabdominal wall, extremities, and spine. LBWC is almost uniformly lethal and associated with a very poor outcome because of, among other factors, pulmonary hypoplasia. The associated anomalies can be significantly disfiguring, often involving extensive lesions of the thoracoabdominal region with visceral herniation, a short or absent umbilical cord, and exteriorization of the fetal heart and bladder. Although what is described as LBWC in the literature includes a highly variable phenotype, clues suggestive of the diagnosis include an asymmetric and/or anteriorly placed cranioschisis (especially if associated with facial cleft); an extensive abdominal wall defect not typical of an omphalocele or gastroschisis; or any concurrence of cranioschisis, limb defect, or thoracoabdominoschisis.

Disorder

Definition

The characteristic defects seen in affected fetuses with LBWC are exencephaly or encephalocele with facial cleft, lateral body wall defect with evisceration, and limb defects.

Prevalence and Epidemiology

LBWC is a rare, sporadic disorder, with an incidence ranging from approximately 0.2 : 10,000 to 1.3 : 10,000 pregnancies.
