A patient with a history of lung cancer: coronal STIR (a) showed several suspicious areas on both tibial bones (arrows in a), which could be misinterpreted as distant recurrence if not noticed to show higher T1 (arrows in b and c) signal than adjacent muscle. Posterior follow-up (d) showed complete resolution of a these areas. This reconversion occurs in a reverse fashion compared to the conversion from haematopoietic marrow to fatty marrow (i.e. the reconversion progresses from the central skeleton to the periphery) [24]
