title: Antenatally diagnosed congenital orbital teratoma in which rupture was associated with intrauterine fetal death.
abstract: We report a case of a fetus with a congenital orbital teratoma (COT), in which rupture of the tumor was associated with an intrauterine fetal demise. An ultrasound scan at 27 weeks' revealed a solid and cystic, complex mass in the orbital region with extensive vascularization suggestive of an orbital cystic teratoma. Magnetic resonance imaging (MRI) supported this diagnosis and clarified tumor localization. At 32 weeks', the patient presented with fetal demise and rupture of the mass was noted. Fetal COTs, like sacrococcygeal teratomas, carry the risk of rupture. MRI in utero is useful for evaluating the extent of disease.
