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

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.

Significance

Most chorangiomas are not clinically significant, i.e. they do not have an adverse affect 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

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