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. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. They can involve a single or multiple ...
It is a hallmark feature of vertebral hemangiomas, a benign vascular tumor of the vertebral body. The sign refers to the appearance of multiple small, dot-like areas of sclerosis or hyperintensity within the vertebral body, resembling a pattern of polka dots.
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
This sign is most commonly identified on lateral radiographs or magnetic resonance imaging (MRI) of the spine and is an important diagnostic marker for benign conditions such as vertebral hemangiomas. Patients with the typical ‘corduroy appearance’ is extremely rare clinically. [2]
Infantile hemangioma is the most common vascular tumor. It is a benign tumor, which occurs in 4-5% of Caucasian infants, but rarely in dark skinned infants. [6] It occurs in 20% of low weight premature infants and 2.2 to 4.5 times more frequently in females. [7]
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus. [6] and formerly known as a cavernous hemangioma.
Congenital hemangiomas are present and fully formed at birth, [5] and only account for 2% of the hemangiomas. They do not have the postnatal phase of proliferation common to infantile hemangiomas. [6] There are two main variants of congenital hemangioma: non-involuting, and rapidly involuting (beginning in the first year of life). [6]
Cavernous hemangiomas of the brain and spinal cord (cerebral cavernous hemangiomas (malformations) (CCM)), can appear at all ages but usually occur in the third to fourth decade of a person's life with no sexual preference. In fact, CCM is present in 0.5% of the population. However, approximately 40% of those with malformations have symptoms.
