What causes Ivory vertebra?
This typical finding on radiography is known as ivory vertebra sign, which is caused by an increase in opacity of a vertebral body, which retains its size and contours, with preserved adjacent intervertebral discs.
What pathology can cause a vertebra to appear ivory white?
Ivory vertebra is sometimes the initial radiologic presentation for common diseases such as prostate carcinoma, lymphoma, and Paget’s disease.
What is Ivory disease?
Traditionally, the ivory vertebra sign has been associated with metastatic disease, especially carcinoma of the prostate or breast, and occasionally with osteosarcoma, carcinoid, Paget disease, and lymphoma, particularly Hodgkin lymphoma (,3).
What is rugger jersey?
Rugger jersey spine describes the prominent endplate densities at multiple contiguous vertebral levels to produce an alternating sclerotic-lucent-sclerotic appearance. This mimics the horizontal stripes of a rugby jersey. This term and pattern are distinctive for hyperparathyroidism.
What is sclerosis of the spine?
Spinal sclerosis is a degenerative condition that impacts the vertebrae and central nervous system, marked by an increased bone density in the affected area. In this article, we will delve into spinal sclerosis and sclerotic bone lesions – what they are, and when to be concerned.
What is picture frame vertebra?
Picture frame vertebral body is a radiologic appearance in which the cortex of the vertebral body is thickened. This sign can be seen in patients with Paget disease. It is a result of disorganized new cortical bone formation after excessive osteoclastic activity causes the resorption of normal bone.
What causes rugger jersey spine?
The image of a rugger-jersey spine is diagnostic for osteosclerosis due to long-standing (untreated) hyperparathyroidism in chronic kidney disease and is caused by a difference in the density of normal mineralized bone and newly formed unmineralized bone (osteoid) at the vertebral endplates.
What is Pott’s paraplegia?
Pott disease is tuberculosis of the spine, usually due to haematogenous spread from other sites, often the lungs. The lower thoracic and upper lumbar vertebrae areas of the spine are most often affected. It causes a kind of tuberculous arthritis of the intervertebral joints.
What does Ivory vertebral bone density mean?
Variations in vertebral bone density are typical of several diseases. The finding of an ivory vertebra means that one or more vertebrae has been affected by a density increase without any changes in the opacity or size of the adjacent intervertebral discs.
What is the Ivory vertebra sign?
The ivory vertebra (also known as ivory vertebra sign) sign refers to the diffuse and homogeneous increase in opacity of a vertebral body that otherwise retains its size and contours, and with no change in the opacity and size of adjacent intervertebral discs.
What is an osteoblastic vertebral lesion (Ivory vertebrae)?
1 Division of Endocrinology and Metabolism, Johns Hopkins Medical Institutions, Baltimore, MD 21287, USA. The differential diagnosis of an osteoblastic vertebral lesion (ivory vertebra) includes metastatic prostate cancer, lung cancer, lymphoma, osteosarcoma and Paget’s disease.
Is there bone erosion at the margins of the intervertebral discs?
There is a density increase of the vertebral body (arrowheads) accompanied by bone erosion (arrows) at the margins of the intervertebral discs and collection (curved arrow) adjacent and anterior to the vertebral bodies (in C). CONCLUSION
