The discovery in the first trimester of an ultrasound anomaly including intra-abdominal anechoic picture is not exceptional and almost all abdominal organs may be involved. However, it has been reported less than 40 cases in the literature and it was most often clinical cases rarely series.
These intra-abdominal anechoic images can be single, multiple and interesser one or more organs at once. Finally, they may be isolated or associated with other anomalies. The prognosis depends mainly on the presence of other morphological abnormalities, the type of body concerned or a chromosomal alteration associated. The management must be multidisciplinary and comes down mostly due to lack of supervision or recommendation to a therapeutic abortion. In any case a neonatal management should be planned.
