El presente trabajo examina el valor de la resonancia magnética (RM) sin y con contraste en el estudio preoperatorio de los hemangioblastomas cerebelosos a propósito de cuatro casos seguidos en nuestro servicio, revisándose la literatura al respecto. Se comparan los resultados obtenidos con las técnicas de neuroimagen convencionales y RM, y se concluye que es éste el procedimiento de elección, si bien ocasionalmente se requiere la práctica de una angiografía vertebral para definir el diagnóstico de presunción.
