Significant amount of joint effusion with intraarticular frond-like fat signal intensity projections (showing high signal intensity on T1/T2 WIs, and suppressed on fat sat series), seen primarily in the suprapatellar and peri-cruciate areas showing peripheral postcontrast enhancement along with diffuse thin synovial wall enhancement without blooming artefacts or bony erosions, features are suggesting lipoma arborescens.
