Paget disease of the hand: radiographic spectrum.

Paget disease uncommonly affects the hand. When it does, radiographic findings are same as when the disease occurs elsewhere. Eleven new cases that demonstrate four predominant radiographic patterns are described: homogeneous sclerosis, trabecular coarsening, cortical thickening, and lysis. The homogeneous sclerosis pattern was associated with monostotic hand disease. One patient developed bilateral phalangeal osteosarcomas. In every case, the disease process extended to the subarticular region and the affected bone was enlarged. With one exception, both ends of the bone were involved.
