Fig. 5. Nonspecific patchy edema in knees in 13-year-old boy who had completed treatment for leukemia and underwent MRI surveillance for development of osteonecrosis to evaluate knee pain.

Fig. 5

A and B, Coronal unenhanced T1-weighted (A) and STIR (B) images of knees show poorly defined decreased signal on T1-weighted and increased signal on STIR images, indicative of edema involving distal femoral and proximal tibial epiphyses and proximal left tibial epiphysis and metaphysis (arrows). These changes resolved at time of follow-up MRI 8 months later.
