A chorionic bump (CB) is a focal irregular bulge in the surrounding choriodecidual due to hematoma. The incidence of CB is between 1.5 and 7 per 1000 pregnancies. The presence of a chorionic bump is associated with a significantly higher risk of adverse perinatal outcomes. CB often decreases in size with time and rarely persists beyond the first trimester. Our case report presents and discusses a chorionic bump diagnosed in the third trimester. To our knowledge, this is the first case of CB to reported in the third trimester.
绒毛凸起（CB）是由于血肿导致绒毛膜下蜕膜周围出现的局灶性不规则隆起。CB 的发生率为每 1000 例妊娠中有 1.5 至 7 例。存在绒毛凸起与不良围产儿结局的风险显著增加相关。随着时间的推移，CB 通常会缩小，很少会持续到孕早期之后。我们的病例报告介绍并讨论了在孕晚期诊断出的绒毛凸起。据我们所知，这是首例报告的孕晚期绒毛凸起病例。
