Female 12 years with history of Blount's disease s/p external fixation of tibial osteotomy (Jan - March 2015) complicated with osteomyelitis (August 2015) now with left proximal tibia radiographic abnormality s/p removal of external fixation, elevated ESR and CRPEXAMINATION: MR right/left knee without and with IV contrast 3/15/2016 Subtle enhancing focus within the left proximal tibial metaphysis, which corresponds to a radiographic lucency on 2/9/2016, with associated cortical thickening. No overlying soft tissue edema or enhancement. No corresponding low T1 signal.Postsurgical changes of a osteotomy along the medial aspect of the left proximal tibia with increased T2 signal within the osteotomy screw tract. Additional areas of enhancement along the right proximal tibial physes likely secondary to epiphysiodesis procedure done on 1/4/2015.
Subtle signal abnormality within the left proximal tibial metaphysis suggestive of post-surgical changes, however, osteomyelitis cannot be excluded.
