ABSTRACT
Chorangiomas affect less than 1% of pregnancies. However, while small chorangiomas are mainly asymptomatic, large placental chorangiomas may lead to severe neonatal and maternal complications. Ultrasound and Doppler technology imaging enable appropriate prenatal diagnosis and surveillance. We present a case of a large chorangioma in a mid-20s primigravid under specialised care at a tertiary referral hospital due to her medical history. The second-trimester scan detected a placental lesion measuring approximately 40 mm, which exhibited significant growth throughout the gestational period. This case was managed by a multidisciplinary team that provided close clinical and imaging surveillance. A caesarean section was performed at 37 weeks due to pre-eclampsia and labour arrest. Both mother and baby were discharged home 3 days postpartum. Histological analysis confirmed the suspected diagnosis of a chorangioma. This case highlights a favourable outcome following conservative management of a large placental chorangioma.
