Figure 3.

MR images and radiograph of the left knee at the age of 4 years and 3 months, after more than 20 months of anakinra treatment. (MRI A: T1-weighted, B: MRI T2-weighted, C: MRI T1-weighted with fat suppression and Ga enhancement, D radiograph). The growth plate widening previously seen (Figure 2) has alleviated with anakinra treatment. A gadolinium-enhanced MR image demonstrates less conspicuous enhancement at the chondroosseous junction after the anakinra treatment.
