Abstract

Congenital intracranial teratoma is a very rare kind of tumor. A fetus was diagnosed with a congenital intracranial teratoma and hydrocephalus at 20 weeks' gestation. On prenatal ultrasonography, the fetus showed a severe macrocephalic hydrocephalus, along with a huge, heterogenous intracranial mass in the posterior fossa. After fetal cephalocentesis was performed at 21 weeks' gestation, the pregnancy was terminated vaginally without any complication. On the postmortem examination, the pathologic report revealed an intracranial immature teratoma. We report a case with a brief review of the literature.

Figure

  • Fig. 1 Prenatal ultrasonographic findings of the cranial transverse plane. Showing about 7.1 cm sized echogenic intracranial mass with ablation of normal brain structure.

  • Fig. 2 Fetal enlarged cranium.

  • Fig. 3 Specimen of fetal intracranial teratoma. There was 8×6×4 cm sized mass on posterior brain parenchyme. The mass had cystic and solid portion and contain some calcification.

  • Fig. 4 Microscopic findings of intracranial teratoma. This teratoma is composed of variable immature and mature embryonal tissues. Immature neuroectodermal tissue (A), ciliated pseudostratified epithelium (B), immature cartilage (C), and liver parenchyme (D). (A, C, D: H&E, ×200) (B: H&E, ×400).
