Abstract:
Cloacal dysgenesis sequence occurs as a result of complete developmental failure of the urorectal septum. Typically, the sequence is featured by a smooth perineum, without any urethral, genital or anal openings. Its clinical manifestation differs throughout gestation. We report an interesting case of first trimester megacystis with associated umbilical cord abnormalities in a female fetus having cloacal dysgenesis sequence. This rare association reflecting high urinary pressure should first suggest urethral atresia. Our case highlights the importance of routine inspection of umbilical cord in the workup of early megacystis in terms of both etiology and fetal diagnosis.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Embryonic Connective Tissues
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

Development of the Sexual Organs in the Embryo and Fetus
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...
