    Fetal gastric pseudomasses, appearing as echogenic areas on prenatal ultrasounds, are typically benign findings in normal pregnancies. These transient masses usually resolve before birth, requiring cautious interpretation by healthcare providers.

    Area of Science:

    • Fetal Medicine
    • Diagnostic Imaging
    • Gastroenterology

    Background:

    • Prenatal sonography is crucial for fetal anomaly detection.
    • Gastric findings during fetal ultrasound require careful evaluation.
    • Understanding transient fetal anomalies aids in accurate diagnosis.

    Purpose of the Study:

    • To describe the sonographic characteristics of discrete echogenic areas in the fetal stomach.
    • To evaluate the clinical significance and natural history of these findings.
    • To provide guidance on the interpretation of fetal gastric pseudomasses.

    Main Methods:

    • Retrospective review of seven prenatal sonograms.
    • Analysis of echogenic area size, texture, and location.
    • Correlation with pregnancy trimester and postnatal outcomes.

    Main Results:

    • Discrete echogenic areas (4-12 mm) were observed in the fetal stomach.
    • These findings were incidental in six normal pregnancies during the second trimester.
    • One case presented in the third trimester with meconium peritonitis; masses resolved in most cases.

    Conclusions:

    • Fetal gastric pseudomasses are typically transient and benign.
    • These echogenic areas may resolve spontaneously on follow-up sonography.
    • Cautious interpretation is advised, considering potential associations with fetal conditions.
