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.
At radiography, this results in increased opacity of the cortex on all sides of the vertebral body.
