Sonolucent areas in the placenta: sonographic and pathologic correlation.

B A Spirt, E H Kagan, R M Rozanski

    AJR. American Journal of Roentgenology
    |December 1, 1978
    PubMed
    Summary

    Gray scale ultrasonography details placental structure. Subchorionic sonolucent areas in term placentas are clinically insignificant, unlike abnormal diffuse intraplacental lesions seen in hydatidiform mole.

    Area of Science:

    • Obstetrics and Gynecology
    • Medical Imaging
    • Fetal Medicine

    Background:

    • Gray scale ultrasonography has advanced the detailed visualization of placental internal structures.
    • Antepartum sonography plays a crucial role in assessing placental morphology and identifying potential abnormalities.

    Observation:

    • Subchorionic sonolucent areas observed on antepartum sonograms correlate with specific histological findings in the term placenta.
    • These sonolucent areas correspond to subchorionic fibrin deposition, hematoma, and cystic degeneration.

    Findings:

    • Subchorionic sonolucent lesions in the term placenta are generally of no clinical significance.
    • Diffuse intraplacental sonolucent cystic lesions represent an abnormal finding.
    • Abnormal intraplacental sonolucent cystic lesions are associated with conditions such as hydatidiform mole and hydropic swelling of the placenta.

    Implications:

    • Ultrasonography can differentiate between clinically insignificant and potentially significant placental abnormalities.
    • Accurate interpretation of placental sonographic findings is essential for appropriate obstetric management.
    • Identifying diffuse intraplacental cystic lesions aids in the diagnosis of specific placental pathologies.
