Large choroid plexus teratoma: A rare cause of congenital hydrocephalus.

ABSTRACT

Teratomas form the most common type of congenital brain tumors, frequently presenting as stillbirth. The largest neonatal series of intracranial teratomas reported a 12% survival rate. Although the first teratoma of the lateral ventricle was reported in 1961 by Maier, neonatal intracranial teratoma of the lateral ventricle is an extremely rare entity. We report here a large intracranial poorly differentiated teratoma arising from choroid plexus of lateral ventricle. This typically presented at birth with a large congenital hydrocephalus.
