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 ...
The polka dot sign is a radiological finding most commonly observed on axial computed tomography (CT) or magnetic resonance imaging (MRI) scans of the spine. [1] It is a hallmark feature of vertebral hemangiomas, a benign vascular tumor of the vertebral body.
On lateral radiographs and sagittal CT of the spine, the corduroy sign appears as vertical linear striations, which are alternating bands of radiolucency (representing vascular spaces) and radiodensity (representing thickened trabeculae) within the vertebral body. The vertebral body may retain its normal shape and size unless the lesion becomes ...
A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. They tend to grow for up to a year before gradually shrinking as the child gets older. A hemangioma may need to be treated if it interferes with vision or breathing or is likely to cause long-term disfigurement.
The spinal cord is a long, cylindrical anatomical structure that is located within the vertebral cavity. It runs from the foramen magnum of the skull to the conus medullaris at the lumbar spine. [1] Most symptoms from spinal tumors occur due to compression of the spinal cord as it plays a primary role in motor and sensory function. [13]
A tufted angioma, also known as an acquired tufted angioma, angioblastoma, angioblastoma of Nakagawa, hypertrophic hemangioma, progressive capillary hemangioma, and tufted hemangioma [1] [2] usually develops in infancy or early childhood on the neck and upper trunk, and is an ill-defined, dull red macule with a mottled appearance, varying from 2 to 5 cm in diameter.
Infantile hemangiomas are the most common type of vascular tumor to affect babies, [4] accounting for 90% of hemangiomas. [5] They are characterised by the abnormal proliferation of endothelial cells and of deviant blood vessel formation or architecture. [6] Hypoxic stress seems to be a major trigger for this. [7]
Glomeruloid hemangioma is a distinctive vascular tumor first described in 1990 when found to be associated with POEMS syndrome and Castleman disease. [ 1 ] [ 2 ] Glomeruloid hemangiomas can manifest as wine-red sessile or pedunculated papules , papulonodules, subcutaneous bluish compressible tumors, or small, firm, reddish-violaceous, dome ...
