Abstract:
Objective To explore the diagnosis and surgical treatment of cerebellar hemangioblastomas (HGBs).
Methods The clinical and imaging features and classifications, as well as the surgery and treatment effects, of 14 cases with cerebellar HGBs were retrospectively analyzed.
Results Standard and contrast-enhanced magnetic resonance imaging (MRI) were performed for all patients. The MRIs revealed five cases with solid HGBs, four with small cysts containing large nodules, and five with large cysts containing small nodules. Cerebral angiography was applied in three of the cases. One case with concurrent aneurysms was found. Microsurgical resection was conducted in 13 cases, with total resections in 12 of the said cases. Satisfactory outcomes were obtained in 12 cases after surgery, which were followed-up for a period of 3 to 51 months. No recurrence was observed in any of these cases.
Conclusion The results of MRI still form the main basis for diagnosing cerebellar HGBs. With the possibility of concurrent aneurysms, cerebral angiography should be considered as part of the routine examination. Microsurgical resection is the preferred treatment for cerebellar HGBs, and neuroendoscopes are valuable for the exploration of nodules in cysts.
