Female 10 years old Reason: History of osteomyelitis, concerning lesion on x-ray on proximal medial tibia Patchy decreased T1 and increased T2 signal of the left tibial proximal metaphysis extending down to the diaphysis. This lesion enhances and is consistent with osteomyelitis. There is similar but less prominent changes in the contralateral side. There is soft tissue edema surrounding the tibia, more prominent on the left.
Findings consistent with osteomyelitis of both proximal tibias, left greater than right. Bilateral presentation raises the question of chronic recurrent multifocal osteomyelitis.
