Sono stati rivisti gli esami TC e RM di 42 pazienti in età pediatrica affetti da tumori del cervelletto e del quarto ventricolo. 14 erano medulloblastomi, 14 astrocitomi, 6 ependimomi, 1 subependimoma, 1 glioblastoma multicentrico, 1 emangioblastoma, 2 gangliogliomi, 2 localizzazioni secondarie, 1 gangliocitoma displastico cerebellare.
Gli aspetti neuroradiologici si discostano in un significativo numero di casi da quelli descritti come classici in letteratura e pertanto si conferma la necessità di un approccio aggressivo per ottenere la diagnosi di natura e di grado di invasività lesionale.
