Thickened diploe of the skull and ill-defined 'fluffy' sclerotic areas most pronounced in the frontal bone.
Case Discussion
The cotton wool appearance is a plain film sign on the lateral skull radiograph in Paget disease.
The appearances result from widening of the diploe of the skull with thickened, disorganized trabeculae.
Sclerotic ill-defined ''patches'' appear fluffy like cotton wool.
