"Aggressive vertebral haemangiomata are a rare form of vertebral haemangiomata where significant vertebral expansion, extra-osseous component with epidural extension, disturbance of blood flow, and occasionally compression fractures can be present causing spinal cord and/or nerve root compression 1,2."
"Accurate preoperative diagnosis is essential because they are highly vascular with a high tendency of intraoperative bleeding. Surgery is required in cases of rapid or progressive neurological symptoms like compressive myelopathy or radiculopathy. Endovascular embolisation prior to surgery to minimise intraoperative blood loss is sometimes performed. Radiotherapy can be used in patients with slowly progressive neurological deficits. Other emerging options in cases of aggressive haemangiomas include radiofrequency ablation with a haemostatic agent (e.g. FLOSEAL, Baxter, USA), and bone autograft placement 6. Minimally invasive procedures may be successful in smaller lesions 5."

"chordoma: can look very similar on T2 and post-contrast imaging, but usually does not have a high T1 signal. Frequent peripheral calcifications can mimic thickened trabeculae of vertebral haemangioma"
