Prenatal diagnosis of placental tumor by ultrasound

Abstract

A case of placental chorioangioma is reported. To our knowledge, this is the first case diagnosed prenatally by ultrasonography, The complications of chorioangiomas include hydramnios, antepartum hemorrhage and premature labor, fetal demise, low birth weight and toxemia.

Ultrasound and Colour Doppler of Placental Chorioangioma with Oligohydramnios

“…The first sonographic diagnosis of a placental chorioangioma was reported by Asokan et al 6 in 1978. Usual grey scale findings include intraplacental subchorionic location, well-defined circumscription, complex echogenicity, which is different from the rest of the placenta, single or multiple tumours and protrusion into the amniotic cavity near the insertion of the umbilical cord.…”

Chorioangioma of Placenta: A Rare Placental Cause for Adverse Fetal Outcome

“…Clarke in 1978 described the first case of chorioangioma [4]. Antenatal ultrasound was reported in 1978, and this has made diagnosis and follow up possible before delivery [2].…”

Chorioangioma of the Placenta

“…This was in 1789 [5]. In 1978, 189 years later, Asokan et al [8] reported the first case of chorioangioma of the placenta in which the diagnosis was made antenatally by ultrasound examination.…”

“…The mechanism by which hydramnios develops is still unclear, probably the pla cental chorioangioma acts as a peripheral arteriovenous shunt causing increased cardiac output and cardiac hy pertrophy in the fetus, congestive heart failure and fluid imbalance. An increased transudation of fluid through the large vascular surface of the tumor, which is aug mented by obstruction of venous return, has also been proposed as causing hydramnios [9], Antepartum hemor rhage occurs in 15-20% of the cases [8], placenta previa, abruptio placenta, abnormal fetal presentation, atonia uteri, premature rupture of the membranes, premature labor and toxemia are other maternal complications that may be associated with chorioangioma [5-7. 9, 10].…”
