Vertebral hemangioma - the current radiation therapy perspective

Vertebral hemangiomas are benign tumors of the spine, most often detected incidentally and on other instances, when signs and symptoms of the disease arise. About 10% of the population are affected worldwide with a female to male ratio of 2:1. The majority of these cases are asymptomatic and no intervention is generally required. Less often, back pain and neurological deficit may occur. Such hemangiomas are termed aggressive by the Enneking staging and warrant treatment. In this review, staging and diagnostics are discussed in detail followed by treatment options. Treatment options entail Surgical intervention, Percutaneous ethanol injection, radiofrequency ablation and Radiation Therapy. There are no set guidelines on preference or order of the treatment options. Further, in this review, studies favouring Radiation therapy regimes and their outcomes are elaborated.
