Intracranial hemangioblastomas: an institutional experience

Area of Science:

• Neurosurgery
• Neurology
• Oncology

Background:

• Intracranial hemangioblastomas are rare tumors.
• Von Hippel-Lindau (VHL) syndrome is a genetic disorder associated with hemangioblastomas.

Purpose of the Study:

• To present institutional experience with intracranial hemangioblastomas.
• To analyze patient demographics, tumor characteristics, treatment outcomes, and recurrence rates.

Main Methods:

• Retrospective study of 69 patients with intracranial hemangioblastomas.
• Data collected over an 11-year period (January 1992 - June 2003).
• Included patient demographics, tumor location, hydrocephalus, surgical interventions, and follow-up data.

Main Results:

• The average age at presentation was 34.5 years, with a male predominance (45 males, 24 females).
• Cerebellar hemispheres, vermis, and brainstem were common locations; 69% of patients had hydrocephalus.
• Mortality was 11%, and 15 patients experienced recurrent lesions during follow-up.

Conclusions:

• Surgical management is generally effective but associated with significant mortality.
• Lifelong surveillance is crucial for early detection of recurrences.
• VHL syndrome patients require particular attention for recurrent hemangioblastomas.
