Abstract
Fetal cervical teratomas are the rare forms of congenital teratomas with a high risk of perinatal morbidity and mortality. Imaging plays an essential role in the management of cervical teratoma and also helps in counselling parents. Ultrasound may be inadequate in the prenatal diagnosis of cervical teratoma due to large tumor size and fetal position. Magnetic resonance imaging could be useful in the in the work-up of tumours detected by ultrasound. We reported a 29-year old pregnant woman referred to our hospital with a finding of giant solid mass at the fetal neck. Ultrasound examination revealed a right-side mass sized 87x64x51 mm that extended from mandible to the anterior thoracic wall. Fetal magnetic resonance imaging provided additional information regarding exact anatomical location and extent of the mass. Thus, we found that fetal magnetic resonance imaging is a complementary diagnostic modality to antenatal ultrasound in the differential diagnosis of cervical teratoma.
