Area of Science:

  • Neuroimaging
  • Fetal Medicine
  • Radiology

Background:

  • Prenatal neurosonography is vital for assessing fetal brain development.
  • Misinterpretation of imaging findings can lead to diagnostic errors.

Purpose of the Study:

  • To identify and describe common anatomic variants and scanning artifacts in fetal brain imaging.
  • To differentiate pseudolesions from true fetal brain pathologies.

Main Methods:

  • Retrospective review of fetal neurosonographic studies from 16 to 36 weeks' gestation.
  • Analysis supervised by a specialist in neonatal cranial sonography.

Main Results:

  • Identified pitfalls in brain parenchyma, ventricular system, and choroid plexus.

  • Provided illustrative images and differentiation clues for pseudolesions.

    • Conclusions:

    • Knowledge of misleading fetal neurosonographic images is essential for accurate interpretation.
    • Distinguishing pseudolesions from true pathology avoids unnecessary invasive testing.
    • Many described pitfalls have not been previously reported in fetal contexts.
