To describe the clinical manifestations and enhance the understanding of outcomes linked to fetal periventricular pseudocysts.
Approach:
Study Design: Retrospective evaluation of 38 pregnant women diagnosed with fetal periventricular pseudocysts between January 2015 and May 2025.
Diagnosis: Diagnosis was confirmed through fetal ultrasound and, in some cases, MRI.
Monitoring: 15 pseudocysts were closely monitored for changes in size during pregnancy.
Key Findings:
Most diagnoses occurred in the third trimester, with 33 out of 38 cases.
Over two-thirds of the pseudocysts were bilateral, primarily located on the lateral aspect of the anterior horn of the lateral ventricle.
Three fetuses had genetic or chromosomal abnormalities.
Two newborns required NICU admission due to infection and prematurity.
Two of the 34 newborns exhibited developmental delays in language and/or motor domains.
Interpretation:
Most fetal periventricular pseudocysts were associated with favorable outcomes, except in cases with additional abnormalities.
Limitations:
Small sample size of 38 cases.
Retrospective nature may limit comprehensive data collection.
Conclusion:
Fetal periventricular pseudocysts are predominantly detected in later trimesters and are often associated with favorable outcomes, particularly when isolated.
