Recurrent or symptomatic residual posterior fossa hemangioblastomas: how are they different from their primary counterparts?

摘要

Background Posterior fossa hemangioblastomas are WHO grade I benign lesions with a surprisingly high recurrence rate. This study determines the factors responsible for recurrence and the clinico-radiological and histopathological differences between primary (group A; n = 60) and recurrent/ symptomatic residual (group B; n = 24) tumors.
