Jaffé and Lichtenstein first coined the term "aneurismal cyst" in 1942 [11] In 1950 they modified this term to "aneurismal bone cyst". They may be associated with bone tumors. The simple bone cyst is a common, benign, fluid-containing lesion, most commonly found in the metaphysis of long bones, typically the proximal humerus or femur ...
The lesion may arise de novo or may arise secondarily within a pre-existing bone tumor, because the abnormal bone causes changes in hemodynamics. An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause ...
CT scans show features such as thin and expanded bony cortex, with or without bony matrix calcifications, and fluid levels due to aneurysmal bone cyst or bleeding within tumour. However, axial views of the subarticular bone (bony area adjacent to the articular cartilage) is not accurate due to voxel signal averaging. MRI is superior than CT on ...
Osteitis fibrosa cystica (/ ˌ ɒ s t i ˈ aɪ t ɪ s f aɪ ˈ b r oʊ s ə ˈ s ɪ s t ɪ k ə / OSS-tee-EYE-tis fy-BROH-sə SIS-tik-ə) is a skeletal disorder resulting in a loss of bone mass, a weakening of the bones as their calcified supporting structures are replaced with fibrous tissue (peritrabecular fibrosis), and the formation of cyst-like brown tumors in and around the bone.
The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).
Eburnation is a degenerative process of bone commonly found in patients with osteoarthritis or non-union of fractures. Friction in the joint causes the reactive conversion of the sub-chondral bone to an ivory-like surface at the site of the cartilage erosion. [1] The word derives from Latin eburneus, which means "of ivory". [2]
A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. [ 1 ] [ 3 ] It is considered to be benign since it does not spread beyond the bone. [ 4 ] Unicameral bone cysts can be classified into two categories: active and latent. [ 4 ]
Loss of bone minerals means a decline in bone mass, thus bones will be weaker in some areas resulting in individuals to be at risk of minor or major falls that could be detrimental. It is known that exercise can allow for stronger bones in order to slow down bone loss in individuals as muscle mass can be built to support and reduce the risks of ...
