Bilateral fetal lungs appear enlarged and diffusely echogenic. Trachea could be seen, of normal caliber (see 3-vessel view). No fetal hydrops or any other obvious anomaly could be visualized.
Echogenic fetal lungs could be due to variety of reasons. In view of diffuse bilateral increase in echogenicity, as well as increased lung volume, possibility of congenital high airways obstruction is being considered.
