Giant Chorioangioma with Oligohydramnion: A Case Report

Chorioangioma or chorangioma is the most common non-trophoblastic benign and angiomatous vascular tumor of the placenta with a prevalence rate of 0.6-1%. It was first described by Clark in 1798. The smaller types of less than 4-5cm occurring in less than 1:10,000 pregnancies tend to be asymptomatic and clinically not significant while larger chorioangiomas found in over 1:16,000 births could manifest with adverse maternal, fetal and neonatal outcomes. The tumor related manifestations in this case report encompass a multitude of features that displayed a placental mass of 8.5 x 8.6cm, oligohydramnion, intrauterine growth restriction, poor biophysical profile and a preterm breech that culminated in an emergency cesarean delivery. The intent of the article is to create awareness of the possible pathology among practitioners, raise a high index of vigilance and establish early diagnosis, prognosticate and enhance the concept of birth preparedness and complication readiness.
