Which condition can cause a ground glass appearance in radiographic images of bones?

The ground glass appearance observed in radiographic images is characteristically associated with fibrous dysplasia. This condition occurs when normal bone is replaced by fibrous tissue, leading to a distinctive radiographic appearance that resembles ground glass. This hazy, translucent quality reflects the disorganized structure of the bone matrix created by the fibrous tissue and is a key diagnostic feature.

In contrast, while Paget's disease can cause abnormalities in bone density and contour, it typically presents with features such as coarsened trabecular patterns rather than a ground glass appearance. Dentinogenesis imperfecta primarily affects dentin in teeth rather than bone, and it is not associated with changes in bone radiography that would produce a ground glass appearance. Kaposi's sarcoma, being a vascular tumor, generally does not exhibit ground glass patterns in bone images; instead, it may present as lytic lesions or other forms of bone remodeling that are not characteristic of the ground glass effect.

Overall, fibrous dysplasia's unique transformation of bone into fibrous connective tissue is what produces the hallmark ground glass radiographic finding.
