However, hemangiomas can become symptomatic in around 1% of cases. Most hemangiomas present asymptomatically and only found incidentally through MRI, CT, or radiography. Typical VHs have predominant fat overgrowth that present throughout various scanning techniques differently compared with atypical VHs that have less fat and more vascular content (see diagnosis). Hemangiomas can display typically and atypically. They can involve a single or multiple vertebrae. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. Vertebral hemangiomas are observed throughout any age, although most are diagnosed in people within their 50s alongside a higher presence in females with a 1:1.5 male-to-female ratio. Symptoms, if they do occur, are usually related to large hemangiomas, trauma, the hormonal and hemodynamic changes of pregnancy (causing intra-spinal bleeding), or osseous expansion and extra-osseous extension into surround soft tissues or epidural region of the spinal canal. They are benign in nature and frequently asymptomatic. Vertebral hemangiomas are a common etiology estimated to be found in 10-12% of humans at autopsy. These are predominantly benign lesions that are often found incidentally during radiology studies for other indications and can involve one or multiple vertebrae. Vertebral hemangiomas or haemangiomas (VHs) are a common vascular lesion found within the vertebral body of the thoracic and lumbar spine. Transarterial embolization, ethanol injection, radiotherapy, and/ or vertebroplasty. Symptoms are dependent on the location and growth of the VHs. If symptoms arise these can include unspecific back pain and neurological complaints (e.g. / ˌ h iː m æ n dʒ i ˈ oʊ m ə/ HEE-man-jee- OH-mə.
