A chorangioma is a non-neoplastic, hamartoma-like growth in the placenta consisting of blood vessels.[1]
Signs and symptoms[]
Most chorangiomas are not clinically significant, i.e. they do not have an adverse effect on placental function.
The significance of a chorangioma is determined by its size and whether it is found together with other chorangiomas. Chorangiomas are significant if multiple or "large", i.e. greater than 4 cm[1] or 5 cm.[2]
Diagnosis[]
Large chorangiomas are diagnosed by ultrasound or MRI,[1] and confirmed by histologic examination of the placenta.
Histologically, chorangioma consist of abundant vascular channels and may be cellular.

Treatment[]
Small chorangiomas are not treated. Large chorangioma can be treated several ways, including chemical ablation and laser coagulation.[1]
