- W4295771816 abstract "To compare ultrasound (US) findings of suspected chorioangioma between cases with confirmed pathology and those without pathology. This is a 10-year retrospective study of pregnancies with suspected placental chorioangioma. Variables examined included middle cerebral artery peak systolic velocity (MCA PSV) measurements, maternal serum alpha fetoprotein (MSAFP), mass size, and US findings. Other variables were birth outcomes and postnatal pathology. Student's t-test and Fisher's exact test were used with significance P < 0.05. There were 43 suspected chorioangiomas, with 14 confirmed by pathology. Positive predictive value was 36.8% There were no significant differences in rates of abnormal genetics, other placental/cord anomalies, mass vascularity, elevated MSAFP, growth restriction, or hydrops. Confirmed cases had higher rates of MCA PSV measurements (85.7% v 10.5%), later gestational age at diagnosis (27.3 v 17.8 weeks) and larger mass size (59.9 v 37.3 mm). Importantly, confirmed cases did not resolve on subsequent US, whereas 31% of other suspected cases resolved. Neonatal outcomes, birth timing, Caesarean rates, birthweight, and neonatal anemia were similar between groups. Chorioangioma is a common placental mass but accuracy of prenatal diagnosis remains low. Classic findings such as vascularity and a well-circumscribed mass do not always correlate with postnatal findings and follow-up US can aid in diagnosis. Neonatal outcomes are favourable with low rates of anemia. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
