Case report and review of the literature. In the past, diagnosis has depended upon the topographical location of the tumor in relation to the tentorium cerebelli. The solid nodules are commonly seen abutting the pia mater.

Adjuvant radiotherapy may be used in patients with incomplete resections. Central nervous system haemangioblastoma: A year study with special reference to von Hippel-Lindau syndrome. The outcome for hemangioblastoma is very good, if surgical extraction of the tumor can be achieved; excision is possible in most cases and permanent neurologic deficit is uncommon and can be avoided yemangioblastoma if the tumor is diagnosed and treated early. Cysts which are within the solid nodule, or have peripheral enhancement, are presumably part of the tumor hemangkoblastoma should, therefore, be resected.

Moreover, hemangioblastomas in patients with VHL have high propensity for tumor growth Hemangioblastomas typically occur in young to middle-aged adults and, although they are the most common primary posterior fossa mass in this demographic, they are nonetheless uncommon in absolute terms.
