FMD, whether in the stage of a fibrous cortical defect or a non-ossifying fibroma, possesses very characteristic radiological appearances which rarely make it necessary to resort to biopsy. In order to avoid mistakes, it is necessary to observe strictly the known radiological features: metaphyseal position, clearcut relationships to the cortex, well defined margins, maximal size 6 to 7 cm., presence during growth, rarely observed in the upper extremity. The differential diagnosis, which needs to be considered only rarely, is discussed.
