Giant Chorioangioma in a Patient with 36 Weeks of Pregnancy: A Case Report

Abstract Present report relates to a 40-year-old patient with 36 weeks of pregnancy and non-trophoblastic benign placental neoplasm chorioangioma (placental hemangioma). The incidence of chorioangioma has been described as 0.5 to 1.0 % of all pregnancies. Tumors may be >4 cm in diameter; such tumors are called giant tumors. Smaller tumors are generally asymptomatic. However, clinically-significant chorioangioma occur less frequently; incidence varying from 1 in 3500 to 1 in 9000 pregnancies. Giant chorioangiomas are very rare tumors; only a few cases have been reported. Feto-maternal complications like fetal growth retardation, anemia and hydrops may develop in a patient with chorioangioma. Further, fetal loss may be as high as ~ 40 %. Increased incidence of chorioangiomas may occur at high-altitude pregnancies, suggesting role of hypobaric hypoxia in pathogenesis of chorioangioma.
