A Case of Congenital Intracranial Immature Teratoma / 대한산부인과학회잡지

ABSTRACT

Congenital intracranial teratoma is a very rare tumor. We recently experienced a case of massive congenital intracranial teratoma that discovered in a male infant of 28 weeks of gestation. A 33-year old multigravida was observed at 28 weeks gestation for prenatal ultrasound examination and ultrasonography revealed the fetus was severely macrocephalic with marked hydrocephalus. For therapeutic termination, Hysterotomy and fetal cephalocentesis was performed to deliver a stillborn infant. Autopsy revealed a 2,420 g male infant with severe macrocephaly. A multilobulated intracerebral tumor was found a diameter 18 cm involving both cerebral hemisphere. The tumor was considered to have originated in the vicinity of pineal gland and suprasellar region. Microscopic examination showed the characteristic picture of a teratoma. The predominent component is immature neuroepithelium in the form of primitive neural tubules variably mature somatic tissure from other germ cell layers accompany the neuroepithelium. We report a case of congenital intracranial immature teratoma.
