Pregnancy outcomes of early pregnancy with chorionic bump: Case series

BACKGROUND: A chorionic bump is an uncommon and localized irregular protrusion of the chorion into the gestational sac on the decidual basalis side, typically identified via ultrasound during early pregnancy. The clinical significance and its association with pregnancy outcomes remain uncertain. OBJECTIVE: To retrospectively analyze 5 cases of chorionic bumps detected by ultrasound in early pregnancy and explore potential associations with embryonic development issues or fetal chromosomal abnormalities. METHODS: Clinical data from 5 patients with chorionic bumps were reviewed. Ultrasound findings, embryonic development, and pregnancy outcomes were examined. RESULTS: The study provides a detailed analysis of the identified cases, with a focus on early pregnancy ultrasound findings and clinical management strategies. CONCLUSION: The presence of chorionic bumps in early pregnancy is a rare occurrence, and further research is needed to determine their impact on pregnancy outcomes, including their potential correlation with fetal developmental abnormalities.
