  • Title: Bilateral Choroid Plexus Papillomas Diagnosed by Prenatal Ultrasound and MRI.
    Author: Li Y, Chetty S, Feldstein VA, Glenn OA.
    Journal: Cureus; 2021 Mar 06; 13(3):e13737. PubMed ID: 33842115.
    Abstract:
    We present a rare prenatal diagnosis of bilateral choroid plexus papillomas by obstetrical ultrasound and fetal MRI at 20 weeks 6 days gestation. The fetus demonstrated bilateral enlarged, echogenic choroid plexus with increased Doppler flow suggestive of vascularized choroid tissue. Same-day fetal MRI demonstrated that the choroid plexus appeared enlarged bilaterally without definite hemorrhage. The combined features on ultrasound and MRI suggested bilateral choroid plexus papillomas with increased cerebrospinal fluid production, leading to ventriculomegaly and enlarged extra-axial spaces. The diagnosis was confirmed by postnatal pathology, which demonstrated WHO grade II atypical choroid plexus papillomas.
