• If no VHL disease is known both symptomatic and asymptomatic hemangioblastomas should be surgically resected completely for histological analysis.
• There is general consent that symptomatic hemangioblastomas should be treated.
• The goal of operative treatment is always the complete resection of the solid tumor component.
• For all cerebellar and spinal hemangioblastomas we recommend a pre-treatment with dexamethasone (4 mg taken 4 times a day) for 3 days and a gradual reduction over the cause of one week after the second postoperative day.
• Preoperative embolization can be helpful in large solid tumors to prevent perioperative hemorrhage.
• In patients with single lesions without VHL disease a 3 months postoperative follow up by MRI with gadolinium is recommended at the site of surgery.
• If radiographic findings show a complete resection of the tumor no further follow up is necessary since recurrences are extremely rare.
• Approximately 5% of patients develop polyglobulia, which can be cured by removing the solid tumor mass.
