The Remediable Metarteriole - Chorangioma

Abstract

Chorioangioma is a benign, non-trophoblastic, vascular neoplasm arising from the placenta. Chorangioma is associated with features such as advanced maternal age, diabetes mellitus, hypertension, preeclampsia, multiple gestations or high-altitude pregnancy. The miniature, asymptomatic chorangioma is incidentally discovered whereas giant chorangioma exceeding >4 centimeters magnitude exemplifies adverse perinatal and foetal outcomes and is associated with intrauterine growth restriction (IUGR), polyhydramnios, preterm labour, arteriovenous shunts, foetal cardiomegaly or foetal heart failure, hydrops foetalis, foetal thrombocytopenia and maternal mirror syndrome. Tumefaction is composed of foetal capillaries circumscribed by stroma and trophoblastic tissue. Foci of tumor infarction, fibrosis, hyalinization, calcification and deposition of hemosiderin pigment are observed. Chorangioma requires a segregation from chorangiosis, chorangiomatosis, inflammatory myofibroblastictumor, Leiomyoma, placental infarct, intervillous thrombus or chorangiocarcinoma. Chorangioma or giant chorioangioma can be suitably discerned with ultrasonography. Treatment options such as draining excessive amniotic fluid or surgical intervention of chorioangioma with laser coagulation and electrosurgical maneuvers may be adopted.
