What is Ivory vertebra?
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 causes vertebral squaring?
Ankylosing spondylitis is the most common cause of vertebral body squaring. It usually involves multiple levels and typically begins in the lumbar spine. Vertebral body squaring occurs after the shiny corner sign/Romanus lesion and precedes bamboo spine.
What is anterior Beaking?
Anterior vertebral body beaking occurs in a number of conditions and may emanate from the central portion or the lower third of the vertebral body.
What is vertebral squaring?
Vertebral squaring, or straightening of the anterior border of the vertebral body, is a well-recognized radiographic feature of spondyloarthritis (1). Squaring can be designated as a pathological change when it occurs in vertebrae in which the normal contour of the anterior border is concave.
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 dagger spine?
The dagger sign is a radiographic feature seen in ankylosing spondylitis as a single central radiodense line on frontal radiographs related to ossification of the supraspinous and interspinous ligaments secondary to enthesitis 1. It is possible for the radiodense line to extent into the sacrum 2.
Can an MRI detect ankylosing spondylitis?
Can you see ankylosing spondylitis on MRI? Yes. An MRI scan of the spine can be used to establish the presence of sacroiliitis or inflammation of the vertebrae, as well as observe bone deposition happening on this part of the spine.
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 Scheuermann’s disease?
Scheuermann kyphosis, also known as Scheuermann disease, juvenile kyphosis or juvenile discogenic disease, is a condition of hyperkyphosis that involves the vertebral bodies and discs of the spine identified by anterior wedging of greater than or equal to 5 degrees in 3 or more adjacent vertebral bodies.
