Fetal ascites

Dr Ammar Haouimi and Radswiki et al.

Fetal ascites refers to the accumulation of free fluid in the fetal abdomen. It is often considered under the same spectrum of hydrops fetalis.

In the case of simple ascites, free anechoic fluid is seen within the fetal abdominal cavity.

General considerations include:

  • fetal pseudoascites: hypoechoic abdominal wall muscles or occasionally the hypoechoic fetal omentum can artefactually mimic a small volume of ascites
