The radiographs show localized diffuse cortical thickening that is characteristic of melorheostosis.

 The condition may be monostotic or it may involve many bones in one extremity (monomelic) in the distribution of a sclerotome. 

Bone scans will show increased uptake at the site or sites of skeletal involvement. 

Long tubular bones are most commonly involved. 

Melorheostosis is usually asymptomatic and requires no treatment. On rare occasions, there may be associated soft-tissue contractures
