Giant Placental Chorioangioma in a Young Patient Causing Adverse Fetal Outcome.

Chorioangiomas are benign vascular tumors of the placenta originating from chorionic tissue. They are also known as hemangiomas of the placenta. They occur in approximately 0.5%-1% of all pregnancies. Large chorioangiomas are rare and may lead to serious fetal and maternal complications. Here, we are describing a case of giant placental chorioangioma in a 19-year-old young female (G2A1) who presented to us at 39 weeks of gestation with decreased fetal movements. Ultrasound examination revealed an enlarged placenta with a well-defined 9.4 cm × 9.3 cm heteroechoic area with increased vascularity. Cesarean section was performed in view of fetal distress and a female baby weighing 1.6 kg was delivered. The newborn died within 2 weeks due to pulmonary hypoplasia and hemodynamic failure. The diagnosis of chorioangioma was confirmed with histopathology. This case depicts the necessity of early diagnosis, close fetal monitoring, and timely intervention in achieving a favorable pregnancy outcome.
