Bone within a bone

Clin Radiol. 2004 Feb;59(2):132-44. doi: 10.1016/s0009-9260(03)00337-4.

Abstract

The "bone within a bone" appearance is a well-recognized radiological term with a variety of causes. It is important to recognize this appearance and also to be aware of the differential diagnosis. A number of common conditions infrequently cause this appearance. Other causes are rare and some remain primarily of historical interest, as they are no longer encountered in clinical practice. In this review we illustrate some of the conditions that can give the bone within a bone appearance and discuss the physiological and pathological aetiology of each where known.
