SACROCOCCYGEAL TERATOMA - A CASE OF MISTAKEN IDENTITY

We report a case in which prenatal diagnosis of fetal myelomeningocele led to termination of the pregnancy at 17 weeks. The diagnosis was ma de on the basis of prenatal ultrasound scan and raised maternal alpha- fetoprotein. Although the large cystic lesion arising in the sacral re gion appeared to confirm the diagnosis, autopsy examination revealed t hat this was a cystic sacrococcygeal teratoma. This case illustrates t he importance of submitting all fetuses for full autopsy.
