Lat X-ray (a) unremarkable, sagittal T2 (b), Sag T1 post-contrast (c), axial T1 (d), and axial T2 (e) show lobulated, mass-like (red arrow) heterogeneous enhanced (yellow arrow) synovial proliferation with characteristic low signal intensity, no articular erosions with large popliteal extra-articular component (white arrow). Sagittal T2 demonstrate massive synovial proliferation with low signal foci of hemosiderin deposition (red arrow)
