Ethanol Injection in Vertebral Hemangiomas
The vertebral hemangioma (VH) is a benign condition, asymptomatic in most cases. However, neurologic symptoms and local pain are sometimes present in relation to morphological changes, fracture, bone expansion, or presence of a soft-tissue mass. Radiologically, VHs are characterized by a thickening of the vertical bone trabeculae, giving a typical striated appearance, and the rarefaction of other trabeculae with vascular proliferation or fat deposition in the medullary spaces. There is no general agreement concerning the possibility of predicting the clinical behavior from radiographs or magnetic resonance imaging (MRI).
