Congenital orbital teratoma: A case report with foetal presentation.

Congenital orbital teratomas are rare entities with few case reports detailing their prenatal and perinatal imaging features. We present the case of a congenital orbital teratoma initially detected as cystic lesion on prenatal ultrasound, with foetal and postnatal imaging showing evolution of characteristic MRI appearances. Knowledge of these appearances and the ability to diagnose these rare entities in foetal life can aid management and operative planning in the immediate postnatal period.
