摘要

Chorioangioma belongs to benign nontrophoblastic primary vascular neoplasms of placenta, originating from primitive chorionic mesenchyme and has a cited prevalence of around 0.6% to 1% of all pregnancies. Though majority of them are asymptomatic, clinical course depends mainly on the size of the neoplasm. Giant chorioangiomas ( 4-5 centimetres in diameter) with an approximate prevalence of around one in 9000 to one in 50,000 pregnancies, have been associated with many adverse maternal and fetal complications. We report a case of 21-year-old primigravida lady, who presented to us at 37weeks 4 days period of gestation with backache and with clinically evident increased liquor. On evaluating the cause of her polyhydramnios, ultrasonography revealed a well-defined echogenic vascular mass measuring ~ 8х8 centimetres in the placenta, suggestive of chorioangioma. Though the condition is infrequent, through this case report, we emphasize that even placental factors need to be ruled out in evaluating causes of polyhydramnios. Despite large size of chorioangioma and associated hydramnios, our patient exceptionally didn’t have any fetal complications. With proper antenatal surveillance, optimal feto-maternal outcome can be expected as seen in our case.
