The salt and pepper sign is used to refer to a speckled appearance of tissue on imaging. It is used in many contexts, but most commonly for the appearance of certain lesions on MRI, especially paragangliomas.
salt and pepper sign (HIV-associated salivary gland disease) 11
salt and pepper sign (juvenile nasopharyngeal angiofibroma) 12
-
salt and pepper skull (hyperparathyroidism)
sometimes confused with raindrop skull of myeloma
NB: pathologists also use the term "salt and pepper", to refer to a distinctive appearance of the chromatin in some diseases 10.
When you think about it, you can probably find folk who have used the term for all sorts of lesions; any lesion that has a fine granular imaging texture will do the trick.
