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. The sign refers to the appearance of multiple small, dot-like areas of sclerosis or ...
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.
Depending on the grade of the sarcoma, it is treated with surgery, [8] chemotherapy, and/or radiotherapy.Though surgery is the current standard of care for hemangiopericytomas, metastasis and tumor recurrence occur in more than 30% of patients, in particular recurrence in the pelvis and retroperitoneum [3] and metastasis in bone and lungs.

Cavernous hemangiomas are erroneously called the most common benign tumors of the liver. [14] Usually one malformation exists, but multiple lesions can occur in the left or right lobe of the liver in 40% of patients. [3] Their sizes can range from a few millimeters to 20 centimetres. Those over 5 cm are often referred to as giant hemangiomas. [3]
Spinal nerve compression and weakening of the vertebral structure cause the symptoms. Pain is the most common symptom at presentation. [ 1 ] [ 3 ] [ 7 ] Other common symptoms of spinal cord compression include muscle weakness, sensory loss , numbness in hands and legs, and rapid onset paralysis .
