A chorangioma is a non-neoplastic, hamartoma-like growth in the placenta consisting of blood vessels.[1]

Diagnosis[edit]

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.

Significance[edit]

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]

Treatment[edit]

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