Objectives: Surgery with complete excision is the best avenue for obliteration of hemangioblastoma. However, in brainstem hemangioblastoma, surgical risks make difficult for exact planning of a surgical strategy. The purpose of this study was to review our experience for hemangioblastoma on cervicomedullary junction with regard to clinical and surgical features.
Materials and Methods: Seven hemangioblastomas in 6 consecutive patients underwent surgical resection in our department between January 2005 and May 2010. Preoperative and postoperative functional outcomes and operative findings were retrospectively reviewed.
Results: The studied patients consisted of 2 men and 4 women aged from 19 to 55 years (mean, 32 years). The most presenting symptoms were headache, followed by deterioration of mental status, hemiparesis and dizziness. Von-Hippel Lindau disease was confirmed in 3 case. Preoperative embolization was performed in 2 cases. All of the targeted lesions were totally resected via midline suboccipital craniotomy and well-demarcated surgical plane from the brainstem. Complications included aspiration pneumonia (2 cases), transient aggravation of hemiparesis and unpredicted pneumothorax (each one cases). There was no permanent neurological deficit except 1 case, consecutively performed surgical removal for huge thoracic hemangioblastoma. In two cases, gamma knife radiosurgery should be performed for remaining cerebellar tumors.
Conclusions: The hemangioblastoma on cervicomedullary junction can be successfully removed with an acceptable level of risk. In selected cases, preoperative emblolization can be helpful in reducing the possibility of intraoperative disasters.
