Chorioangioma of placenta: a rare placental cause for adverse fetal outcome

Chorioangioma is a benign angioma of placenta arising from chorionic tissue. Large chorioangiomas are usually associated with adverse fetal or maternal outcome such as fetal growth restriction, polyhydramnios, fetal anemia, intrauterine fetal distress, intrauterine fetal demise, preterm delivery, premature rupture of membrane and sometimes association with pre-eclampsia in the mother. Here we are reporting a case of 35 years old primigravida who was diagnosed with large chorioangioma of 7.1×4.8×5.0 cm on her 28-32 weeks growth scan with estimated fetal weight of 2.259 kgs. She was having regular antenatal checkups previously. Her previous ultrasounds were reported normal. There were no abnormal findings like fetal growth restriction, polyhydramnios, signs of fetal anemia and all doppler parameters were normal. Usually, large Chorioangiomas are associated with complications. This placental growth seen only at 32 weeks it did not lead to any complications and patient had an uneventful delivery. However large Chorioangiomas require strict monitoring by ultrasound and doppler studies for fetal and maternal well being.
