El conocimiento de los gliomas de tronco ha sufrido una importante progresión en las dos últimas décadas, siendo considerados en la actualidad un grupo heterogéneo de lesiones con especial predilección por la edad infantil, donde alcanzan un 10–20% de los tumores cerebrales. Además del tradicional tumor difuso, se han identificado subgrupos biológicamente diferentes, susceptibles de resección quirúrgica y con mejores expectativas pronosticas, lo que ha dado lugar a numerosas definiciones y clasificaciones. Por otra parte, recientemente se ha prestado atención a los rasgos especiales que presentan los gliomas de tronco en la edad adulta. Basados en una revisión de la literatura existente, describimos los diferentes tipos conocidos de gliomas de tronco, con particular interés sobre las modalidades terapéuticas y las diferencias entre los tumores pediátricos y los del adulto, empleando iconografía propia.
Brainstem gliomas have been increasingly unders-tood in the last two decades and they are nowadays regarded as an heterogeneous group of tumors with tendency towards the pediatric age, where they account for 10–20% of brain neoplasms. Besides the well known diffuse tumor, several subtypes, with a different biologi-cal behaviour, amenable to surgical resection and better prognosis, have been identified, giving rise to many classifications and terms. In the other way, attention has been recently paid to adult brainstem gliomas in contrast to pediatric tumors. Based on a review of the literature, we describe the different subtypes of brainstem gliomas, with particular interest on therapeutic approaches and differences between pediatric and adult tumors, employing iconography from our series.
