The breast within a breast sign, also known as cut sausage appearance, refers to the common mammographic appearance of breast hamartomas (fibroadenolipomas). Since these benign lesions are well-circumscribed encapsulated and contain a mixture of fibrous, glandular and fatty tissue (just like normal breast), it is not surprising that they appear very much like a second breast sitting within a breast.
