title: Early-stage hemangioblastoma presenting as a small lesion with significant edema in the cerebellum.
abstract: Hemangioblastomas are benign tumors that are frequently associated with peritumoral cysts; however, their early characteristics before cyst formation remain unclear. In this article, the authors present a novel case of a cerebellar hemangioblastoma presenting as a small solid lesion with significant edema. Surgery was performed to resect the tumor, and a follow-up magnetic resonance imaging scan revealed complete excision of the mass and resolution of the cerebellar edema. Histological examination confirmed that the lesion was a hemangioblastoma. This is the only report in the literature to describe the imaging and histopathologic characteristics of an initial hemangioblastoma in the cerebellum.
