Discordant Anomalies with Combined Features of Pentalogy of Cantrell and OEIS Complex: A Case Report in Monochorionic Twins

Introduction: Ventral body wall defects have various manifestations. Among others, pentalogy of Cantrell (PC) and omphalocele exstrophy imperforate anus spinal abnormalities (OEIS) complex are defects that involve upper and lower anterior midline of body wall, respectively. Although both entities are in a spectrum of ventral body wall defects, the combination of PC and OEIS complex has not been described. Case Report: In this report, we describe an unusual case of congenital ventral body wall defect with combined features of PC and OEIS complex, which discordantly occurred in monochorionic monoamniotic twins. Conclusion: PC and OEIS complex may be related regarding their embryologic origins. The combination may represent the most severe manifestation of ventral body wall defects.
