Revision 7 for 'Cotton wool appearance of bone'
Cotton wool appearance of bone
The cotton wool appearance is a plain film sign of Paget's disease and results from thickened, disorganized trabeculae which lead to areas of sclerosis in a previously lucent area of bone - typically the skull. These sclerotic patches are poorly defined and fluffy.
