Multimodal Management of Spinal Cord Hemangioblastomas: A Comprehensive Review

Spinal cord hemangioblastomas are rare, benign, and highly vascular tumors that occur sporadically or in association with von Hippel–Lindau disease. Despite their histological benignity, they often cause significant morbidity due to progressive neurological deficits, syrinx formation, and recurrence in the von Hippel-Lindau population. We performed a comprehensive review of the literature by searching PubMed, EMBASE, and Scopus for studies published in English on spinal cord hemangioblastomas. Eligible studies included original research, case series, and case reports with explicit clinical outcomes or management strategies for pathologically or radiographically confirmed SCHb. Gross total resection is feasible in most cases, leading to durable tumor control and favorable neurological outcomes. Preoperative embolization has been employed selectively to reduce intraoperative bleeding. Radiotherapy, particularly stereotactic radiosurgery, has shown promising local control for surgically inaccessible or recurrent lesions, while conventional external beam approaches provide less consistent results. Anti-angiogenic agents have demonstrated anecdotal benefit, and the HIF-2α inhibitor belzutifan represents the first systemic therapy approved by the FDA for VHL-associated hemangioblastomas. The management of SCHb requires an individualized, multimodal strategy. Microsurgery remains the cornerstone of treatment; radiotherapy and pharmacotherapy are valuable adjuncts for specific clinical scenarios. Further prospective studies are needed to optimize patient selection and integration of these therapies.
