Congenital brain tumors are extremely rare. Among them teratomas are the most common. They make up one-third of all congenital brain tumors. Late diagnosis, poor prognosis, and majority being delivered by cesarean section (subjecting the mother to increased morbidity) add to the complexities and challenges of the case. We report a rare case of a massive congenital brain tumor diagnosed prenatally on ultrasound. Because of the poor prognosis and associated craniomegaly, pregnancy termination was contemplated at 28 weeks aiming at vaginal delivery, despite a high probability of an eventual cesarean delivery due to the associated macrocrania. Intrapartum second stage of labor was protracted due to nondescent of the large head; however, providentially there was timely skull rupture of the fetus facilitating a vaginal delivery. The cerebral tumor was confirmed at autopsy to be an immature teratoma. There were no other associated malformations. Ultrasound has emerged as major modality in prenatal diagnosis aiding the antenatal preparation of the prospective parents and the multidisciplinary team for the poor outcome. The knowledge gained and anticipated prognosis help immensely in planning the management, thereby avoiding subjecting the woman to cesarean section and its morbidity.

Los tumores intracraneales fetales son poco comunes, pero cuando aparecen están asociados con una elevada mortalidad. Muchos de los tumores cerebrales congénitos a menudo provocan la muerte fetal intrauterina, lo que limita la evaluación precisa de su prevalencia e incidencia del tumor. El más frecuente es el teratoma, que se caracteriza por estar constituido por células dependientes de las tres capas germinales. Estos tumores suelen detectarse en las ecografías habituales de control prenatal y, frecuentemente, son tan grandes que se dificulta determinar su origen. Por ello, ante la sospecha ecográfica, se recomienda completar el estudio con una RM fetal. Se presenta un caso de una gestante de 20 semanas, en quien se detecta un tumor intracraneal fetal en una ecografía de control prenatal. Se decide completar el estudio con una RM fetal en la que se visualiza una masa dependiente de la glándula pineal con extensión anterior, compatible con teratoma. Se decidió la interrupción voluntaria del embarazo, y en el estudio histológico tras la necropsia se confirmó un teratoma inmaduro. La RM es la prueba de imagen de elección tras la sospecha diagnóstica ecográfica. Por su alta resolución aporta información relevante que permite valorar mejor la arquitectura interna del tumor, así como su origen y extensión. Además, sirve para evaluar el resto de estructuras intracraneales.
