Background And Objectives:
We present our experience in the management of symptomatic vertebral hemangiomas with epidural extension (SVHEE) using spine stereotactic radiosurgery (SSRS).
Methods:
An Institutional Review Board approved retrospective review of all SVHEE patients treated with SSRS at our institution (2007-2022) was performed. Baseline patient demographics, clinical presentation, lesion volume, and Bilsky grade (to directly evaluate the epidural component) were determined. Clinical and radiographic response and treatment outcomes were subsequently evaluated at first (∼6 months) and final follow-up.
Results:
Fourteen patients with SVHEE underwent SSRS (16-18 Gy/1-fraction); the mean follow-up was 24 months. The median lesion volume (cc) was 36.9 (range: 7.02-94.1), 31.5 (range: 6.53-69.7), and 25.15 (range: 6.01-52.5) at pre-SSRS, first, and final follow-up, respectively. Overall volume reduction was seen in the last follow-up in all 14 patients, median 29.01% (range: 6.58%-71.58%). Bilsky score was stable or improved in all patients at the last follow-up when compared with pre-SSRS score. Patients who underwent both surgical decompression and SSRS (n = 9): 8 had improved myelopathic symptoms and pain and 1 had stable radiculopathy postintervention. In the 5 patients treated with SSRS monotherapy, 2 had stable radicular pain and the other 3 improved pain and numbness. No patients experienced adverse outcomes.
Conclusion:
To our knowledge, this represents the largest series of SVHEE patients treated with SSRS, either as monotherapy or part of a multimodal/separation surgery treatment approach. We demonstrate that SSRS represents a potentially safe and effective treatment option in these patients. However, larger prospective studies and longer follow-ups are necessary to further assess the role, durability, and toxicity of SSRS in the management of these patients.
