Introduction:
Body stalk anomaly (BSA) is a rare and severe congenital malformation in which the exact pathophysiology is still unknown. The possible causes of body stalk anomaly include early amnion rupture with direct mechanical pressure and amniotic bands, vascular disruption of the early embryo, or an abnormality in the germinal disk.
Case Presentation:
We report a case of sonologically delayed diagnosis of BSA which was confirmed post-delivery following histopathological examination and we reviewed relevant literature regarding this phenomenon. Sonographic features of the foetus included a wide anterior abdominal wall defect (omphalocele) with protrusion of the liver into the amniotic cavity. The umbilical arteries show normal calibre, flow, velocimetry, and spectral waveform.
Conclusion:
Body stalk anomaly is accepted as a fatal anomaly, so it is important to differentiate it from other anterior abdominal wall defects prenatally and this could guide the management options.

Notch Signaling Pathway
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
