Imaging Procedures and Findings

Multiple lytic lesion in skull , without periosteal reaction . both tables being involved . other lesions in humerus and femur are seen.



This is a more chronic form of the disease, with dissemination of lesions in the lungs, lymph nodes, liver and spleen, in addition to virtually constant and early involvement of the skeleton. The bone defects are essentially the same as those of eosinophilic granulomas.They are far more umerous and particularly affect the flat bones. In the skull they often coalesce to produce widespread irregular defects usually likened to a map and described as the `geo graphical skull', both tables often being involved.
