Highlights

•	Cervical spinal hemangioblastoma (CSHBs) has rarely been reported in the cervical spine, and microsurgical treatment even less.
•	The study included eleven patients with CSHB treated by total tumor resection from January 2005 to December 2015.
•	Finding and blocking nutrient arteries during the operation is necessary to reduce bleeding.
•	All patients in this study were in good postoperative health, without recurrence during 6-48 months’ follow-up.
•	A discussion of a series deals with surgical considerations.

Abstract

Background: Hemangioblastoma is a rare intracranial vascular tumor, mostly found in the cerebellum. Cervical spinal hemangioblastoma (CSHB) has rarely been reported, and microsurgical treatment even less.

Objective: To present our experience with CSHB and conduct a literature review, in order to provide a systematic approach to diagnosis and microsurgical treatment.

Methods: The study included 11 patients with CSHB treated by total tumor resection from January 2005 to December 2015. We analyzed clinical and radiological data, surgical outcome, and pathological examination results.

Results: All patients were treated by total tumor resection. All preoperative nerve root pain resolved completely. Four patients had associated numbness, which improved in 2 and persisted in 2. All patients were in good postoperative health. There were no recurrences during follow-up of 6-48 months.

Conclusion: Preoperative magnetic resonance imaging (MRI) and computed tomography angiography (CTA) can be used for diagnosis of CSHB. Finding and blocking the nutrient arteries during surgery is necessary reduce bleeding. Total tumor resection requires accurately identifying and separating the proliferative area around the tumor.
