[Course of Paget's osteodystrophia deformans--exemplified by the roentgen morphology of the cranial bones].

The still unknown etiology and pathogenesis of Paget's disease or Osteodystrophia deformans Paget are discussed; localisation of skeletal lesions and clinical findings of the disease are described. The skull bones are used to give an example for the 4 phases of the course of the disease, shown by X-ray pictures. Typical X-ray findings of changes in structure, pattern, size, and shape of the skull bones are compared with the pathological and anatomical picture.
