MRI changes of the bone condition. Oblique sagittal pre- and postcontrast T1 TSE images with fat suppression of the left TMJ of a 16-year-old girl (case 10) without improvement in inflammation: joint enhancement is only minimally reduced from baseline (a, b) to 2-months after IAC (c, d). She was under MTX treatment. At 2-year follow up, with a repeated injection 11 months after baseline, there is some reduction in joint enhancement (blue arrow), but the disc has become perforated and the condylar surface discretely more flattened and irregular (red arrow) (e, f). Oblique sagittal T1 TSE images with fat suppression of the right TMJ of a 15-year-old girl (case 9) with improved bone condition: discretely flattened and irregular condyle (blue arrow) at baseline (g) has become smooth and more rounded (blue arrow) at 2-year follow-up after IAC and systemic treatment with biologics and MTX (h)
