Fetal intracranial immature teratoma: presentation of a case and a systematic review of the literature

“…It is the second most frequent location after the sacrococcygeal tumors (4). At intracranial level, mainly supratentorial, they originate in the hyophysis, the suprasellar region, third ventricle, and brain hemispheres, being impossible in the majority of cases to determine the exact tumor origin (as in the case presented here) (3,10,14,15). From their development in the mid-line, they often extend from the intracranial area to the third ventricle, causing a hydrocephalus typical of these (also present in our case).…”

“…However, extracranial growth to the orbits is possible, as well as to the nose, oropharynx, neck, etc… Being the worse prognosis (4,15).…”

“…Prior to establishing the definitive diagnosis, we should rule out possible hemorrhage, vascular malformation, or a rare entity, but we must not forget the so-called 'fetus in J U S T A C C E P T E D fetus', and that it consists of the presence of a mass with fetal characteristics within a normal fetus, and being able to show cardiac activity in its interior (4,10,15).…”
