Salt and pepper sign (skull)

Salt and pepper sign or pepperpot skull of the calvarium refers to multiple tiny well-defined lucencies in the skull vault caused by resorption of trabecular bone in hyperparathyroidism.

There is a loss of definition between the inner and outer tables of the skull and a ground-glass appearance as well as spotty deossification.
